Hello Guru,

My honda 2002 is not selecting gear at all. What do I do? Can you recommend a gear expert based in Abuja?

Your gear is bad sir. I would highly recommend a gear replacement. You can speak to Kingreign on the forum.

Hello sir

What are are we talking about here sir?

here for you!

ApolitiCal:
Please compare RX330, 07 rav 4, 07 ford edge, and Acura rdx putting everything into consideration. Also, choose one for me as my first car. Thanks.

These are cars from various classes.

For economy and affordability and prestige , i will rate them in the following order: 07 Rav4, 07 Acura RDX, 07 Ford Edge, RX 330

double3:
Response well appreciated...thanks

you are welcome sir.

Please I've come to observe the 09 corolla ain't as popular as the 04-06 model, are there any faults or issues related to that model (09) cos I'm thinking about getting one....thanks in anticipation

Thank you sir for your inquiry.

It is a lot more popular for the following reasons:

Easier to run and maintain. Almost any mechanic apprentice can work on it.
Cheaper engine and transmission ( if there is ever any need for a replacement)
Cheaper parts and very readily available in most markets across Nigeria
AC system more robust unlike the 09 model which uses the VDC compressor type. AC parts are also very cheap and easy to repair
I could go on and on.

But please note that the 09 model is also very reliable in its own right.

Hello motor Guru/everyone,

I use a Honda 2006 model. I’ve been having this constant issues with car overheating when I switch on the AC. However, it is every important to note that I’ve done everything possible to to rectify this anomaly. Basically, all necessary cooling stuffs are working. The fan is working perfect (2 fans), I’ve had the radiator washed out (which is a double cell radiator).. But the car overheats while the Ac is On still. It sometimes goes off while in motion.. I’ve to switch off the AC and after a minute or two, car picks off.

Highlight

1) Car overheating inspites having the fan working perfect, double cell radiator watched out recently, and as well as radiator coolant. It’s important to note that the fan Belt is working perfect.

2) When the AC is on, if the car doesn’t overheat in motion, it sometimes goes off abruptly. Until I switch off the AC and wait for few minutes before it picks up.

I’ve spent lot of money on trial and error mechanics but not sure what the exact cause might be. I’m considering changing the Fuel pump but I don’t wanna waste money since the exact cause isn’t identified yet.

Kindly help cause the weather is hot and need 24/7 AC while driving. Thanks in advance...

You can also recommend a very good auto clinic here in Ibadan.

Sorry for the inconvenience sir.

Please kindly anser the following questions:
Has the fan circuit ever been modified to run directly?
Has the airflow of the fan operation been checked? When operating, it should suck in air e.g. putting a piece of paper in-front of the condenser/radiator should stick when the fans are running
Has your ac condenser been checked to ensure it is working fine(e.g the fins clear)? Or has the condenser been changed before?
Has the engine been worked on before?
Is your AC compressor pump working normally(not binding)?

Has your radiator been bled properly( i.e. no air in the system)?

You can check the moniker Gazzuzz on the forum. He should be able to recommend a mechanic for you in Ibadan

Oh, fuel filter , my mind was programmed to oil filter ..

ok sir.

so kindly act on it and revert

JhaayYoung:
I think it is the first option of restriction in the fuel supplied cos of how it struggles to stay ON when in Idle .i notice it’s been guzzling fuel too. I just serviced with recommended fuel filter, so I don’t think the fuel filter is the issue .
But, I am not tech savvy. I don’t know what to do.

When you said service, did you mean washing the filter or outright replacement?
And when I said filter, I did not mean the screen attached to the fuel pump.

JhaayYoung:
These are the codes detected . Please, what is to be done .

Sorry for the inconvience sir.

The first code P0171 implies the your engine management system is either having a serious restriction in your fuel supply system or you have a vacuum leak . this means your ecu is trying to compensate for this by adding more fuel( increasing injector/nozzle pulse width) and its threshold has been exceeded.

Check the following areas( in the following order)
1. Ensure all vacuum lines are connected and not leaking anywhere. Ensure you are not hearing any 'hissing' noise.
2. Check and ensure your fuel filter is not clogged. The ideal way to check this is by hooking up a pressure gauge in series to the fuel line. The other way is by removing the fuel pump assembly( from the fuel tank ) and separate and visually inspect the fuel filter
3.ensure you do not have leaks in your exhaust system ( particularly before the air/fuel ratio sensor).

The remaining misfire code ( misfire on all cylinders ) would imply a compromise in your fuel supply system. There may be dirt your system which might have been as a result of point 2 above and the lean code( P0171). Please note that a misfire can be caused by many things, but in this case, I would seriously look at your fuel supply system.

My advice? After point 1 has been investigated, replace your fuel filter or better, your fuel pump assembly.

JhaayYoung:
Thanks for the response , I just got a Bluetooth OBD II scanner , I will scan and drop codes here

ok sir

JhaayYoung:
Hello sir, I got a Tokunbo Toyota 2003 Matrix with the check Engine light on . I was told it would go away after servicing . I serviced with recommended oil purchased from trusted source . Mobil 1 full synthetic . The light isn’t still off and I noticed when it is idling, there is a really slight vibration. I don’t have a scanner but I just want to know the possible causes till I get a competent mechanic shop to take it

Sorry sir for the late response.
For your check engine light to be on, it means there is something wrong in your emissions system or power-train.
Changing engine oil may not necessarily turn it off. I suggest you go for a scan to let us know exactly what the problem is.

HeavenlyBang:
Thanks for the reply!

Are they actually effective? By how much?
Possible negative effects?
You're a technician, I think. What are your hands-on experiences with boosters?

Thank you sir
as per your concerns:
1. For minimizing the risk of pre-ignition in cars that require premium fuel, they are quite effective.By how much now depends on the available brands that and their levels of efficacy.
2. Ideally, the use of octane boosters should be as a last resort. The ideal solution should be the use of premium fuel ONLY(RON 93 or higher) This is because octane boosters contains compounds that overtime clogs Fuel injectors and other fuel components which would then require periodic cleaning from time to time(if not, misfires may arise)

But this is Nigeria. Even the regular grade fuel , we are not sure if the rating is 87. + the adulterated nature of the petrol being imported into this country.

Until the classification and quality control of petrol according RON is common place, the use of Octane Boosters remains the better devil.

HeavenlyBang:
Thoughts on octane boosters?

Thank you sir for your comment.

The use of octane boosters has become commonplace( and by implication necessary) in Nigeria due to the influx of high end luxury cars whose engines have been designed to run on premium fuel (RON 93 or higher) for optimum engine performance and minimizing the likelihood of having pre-ignition concerns (due to very high compression ratios) when using the available fuel (RON 87 or lower ) at our pump-stations over the country. This is because a lower octane fuel than what is recommended can damage such engines and catalytic converters in the long term as it causes ‘knocks’ or irregular ignition.

Therefore, Octane boosters are basically additives to your fuel to increase the octane number of the fuel. These additives, which may include alcohols, ether, manganese or other chemicals improve the performance of the engine in terms of either acceleration, top end speed, efficiency and horsepower.

Please note that octane boosters have negligible or no effect on low performance road-going cars. If a vehicle manufacture has recommended a RON rating 87, using octane boosters will be a waste of money.

My opinion? If your vehicle requires(not recommends) premium fuel, then you may have to use octane boosters.
In the case your vehicle requires octane boosters, ensure you buy octane boosters from reputable brands.

N.B. This is why Some Lexus brands will always be expensive in Nigeria (if you know what i mean)

here for your concerns

thanks motor guru for your kind gesture
had my mechanic change d plugs, engine oil with mobile xhp, abro power steering fluid.
pls can i see a picture of idle control valve and it location in the engine
can i use mobile for ATF and what brand

Pls find attached the pic of the Idle control valve location on your car.
Pls sir DO NOT USE moblie atf for your car. Use only Genuine Honda DW1 ATF only.

kayphyzee:
Thank you for the heads up.

You are welcome sir.

bluejay242001:
Thank you so much for the way you give detail analysis of car issues.
i have honda pilot 2004. i discovered that each time i buy fuel from a particular fuel station my engine light comes on.
Also i gave my brother my car to service because i was busy he used conoil golden oil instead of mobil.....
1. what should i do
2. should i use honda-synthetic-blend-5w20-advanced-protection-engine-oil and Honda ATF- DW1 AUTOMATIC TRANSMISSION FLUID.
3. where can i get this honda product from...
4. is it advisable to use this
will be very grateful if u respond to my question.... Thank you and God bless you.

Thank you sir for your kind words
1. I would advise you stop buying fuel from that particular filling station. It is likely their fuel is contaminated.
2. These are proprietary fluids by Honda for Honda vehicles.You might be a bit flexible with the engine oil (by going for fully synthetic 5w20 from reputable brands like MObil1). But for the ATF fluid , please stick only to the Honda ATF DW1 fluid ONLY)
3. You can contact Gazzuzz for the Engine oil and Luvinhubby for the Honda ATF.
By the way, If you intend using Mobil and buying from any other seller, ensure that it is original to avoid engine damage. There are so many fakes out there.

umennaesie:
Hello good morning Oga motor guru and Gazzuzz
please i need guide on the following issues.
my car is Honda accord baby boy 2002 model 4 cylinder engine
1. recommended Engine oil
2. recommended ATF for it. was told of MOBILE ATF/ OANDO/TOTAL ATF. but been scared and skeptical as i dont know which one was used by the former owner
3. Does it have AT filter and does it need replacement
4. engine vibrate some times especially first time in morning when i start the car
5. fuel economy is really not to encouraging
6. Trip A and B on odometer
please need your take on this.

Thank you sir for your inquiry.
1. The recommended Engine oil for your car is any reputable brand with of 5W30 grade You can contact Gazzuzz for your Engine oil as he sells original Mobil 1 synthetic engine oil of various available viscosities.
2. The ONLY recommended atf for your gearbox is Genuine Honda DW1 atf fluid. Please do not use any other fluid for your car. You can contact Luvinhubby on this forum.
3.The gearbox of your car has an AT filter but unfortunately this is not serviceable, as it is within the gearbox. This means that replacement of the filter will require gearbox removal and dismantling.
4. You might need an engine Tuneup and a cleaning of your idle control valve
5. you might need a tune up( sparkplug change, air filter etc.) also scan your car for codes to be sure your engine management system is working properly.
6. I do not understand you last point sir. Please could you explain better?

here for you

Dear MotorGuru,


My issue has to do with the transmission of a 2001 Rav4 that I just got. After purchase, I had my mechanic drain the transmission fluid inside and replace with Toyota Type T-IV. I decided to take it with me on the family Christmas trip and noticed that it wouldn't go beyond gear 3 (80km/hr at 3100rpm). Even when I fire up to 4000rpm, it still wouldn't engage gear 4. All through the trip, I left the speed at 80km/hr (3100rpm).

Apart from that issue, I noticed that the Reverse gear when engaged would sometimes give noticeable jerks and the accelerator depressed. Other times, it moves fine.

I'd like your opinion on what's going on and how to rectify same. Many thanks.

Sorry sir for the predicament.

I will seriously advise that you take the car for a diagnostic scan. It is very likely you have a defective ECU/ brainbox. This is a common issue with 2001 to 2003 Toyota rav4s. Driving the car like that will ultimately damage the gearbox mechanically. If after scanning, you have transmission related codes, then you will have to replace the brain box or repair it. Pls stop driving the car for now.

Sircreeden:
Thank you very much please is there anyway you can inspect cars for me I will pay for all your services I'm currently in Lagos now

Thank you sir. Unfortunately at the moment we do not offer such services. But you can visit the Monikers Gazzuzz and Mayor2013 on this forum. They should be able to help you out with your needs.

Grilovictor5:
Thanks for the advises. The Camry is 2008 model, is not smoking I have checked that when I ask someone to drive behind me and there is no leakage of such. I was told to change from Mobil oil to total oil.

The 2nd generation 2AZ-FE engine installed in the 2007-09 camry and 2006-08 Rav4, were revised with new pistons and rings , which unfortunately defective with respect to oil control. they carboned up easily and then ultimately lead to increase oil consumption in as early as 70,000 miles. this led to class action suits in the US forcing Toyota to perform oil consumption test and ultimately replacing the Pistons and rings for free.

It is very likely your camry is a victim to this, and therefore your only option maybe to rebuild your engine(by replacing the pistons and rings with the EXACT REVISED PART) or replace your engine.

If you are going for a rebuild, Please note that the pistons and rings MUST be specific to the 2AZ-FE in your car. The pistons and rings of the 1st generation 2AZ-FE (found in 2002-2006 camry, 2004-2005 Toyota Rav4 and 2001-2007 Toyota highlander) WILL NOT BE COMPATIBLE.

If you go ahead with such installation without this caution, serious piston slap will occur.

Happy new year.
Still await your feedback.

Sorry for the late response sir.

Since it is a 2005, it is not equipped with 'drive by wire' (electronic throttle control) but instead has a cable controlled throttle body with idle air control valve.

My recommendation is that you remove both the idle air control valve and throttle body and thoroughly clean with carburetor cleaner, reinstall and perform an idle relearn procedure.

please do this and get back to us.

Sircreeden:
Happy New Year to you motorguru..

Please I'm abit confused now I was planning on getting a Nigeria used Benz E320 after you explained about the SBC of which the seller told me is faulty also said the AC is leaking so I ran lol ....

Now I have another two set of used Nigeria cars again lol but I need your kind advice

Infinite fx35 2005 and BMW x3 2005

Which in terms of Cheap parts and low fuel consumption....but I think both are 6v engines

Happy new year sir.
What is the engine displacement of the BMW x3?

All the same, both are from the luxury car niche, both offer sporty drive experience, and both are practically useless when it comes to real off-road work demand
The FX35 is a heavier car, so expect a worse fuel economy compared with the x3.
Both have good and proven engines( if you are considering the X3 with a M54 engine), but expect some oil consumption with the Infiniti VQ engine at higher mileages.
Both require premium fuel
The BMW might cost you more maintenance wise as it ages. you might experience some electrical gremlins. The Infiniti is not too far off on this.
Both are ok cars, if you have a deep pocket.
Please ensure you perform comprehensive inspection and checks before you purchase.

Happy new year!

Hello sir,

Any car can be converted, as long as it was designed from inception to have LHD and RHD configurations. Some cars are dated easy to convert( most European cars), while some are difficult , requiring the removal and replacement of the engine firewall bulkhead( Some Japanese brands), if you want to do it professionally.

What car are we talking about here sir?


Motorguru

Sorry sir for the predicament.
What is the color of the smoke? Is it pure white? Bluish white? Black?

If it is pure white, you may have to focus on your diesel injectors.you may have bought bad diesel , and the fuel cannot burn properly. In this case, severe engine performance issues will occur(lack of power).

If it is bluish white, then your piston rings or valve stem seals or pcv valve may be damaged.

If it is black, then your injectors may need to be recalibrated, as the car is burning too much fuel.or you may need to check your emission control system by performing a scan.
