OP I just stumble to this page and very happy to discover your great insight and help you render in this forum. Kudos to you. My Mazda 626 (2000) is having this issue of not steaming normal when you start the car.
Immediately you start the car and remove your leg from the throttle, it will just go off.
What may be the cause?

hello house,

my Honda DC gear stick flickers on the dashboard when i try changing gears, the transmission is perfect, gears change normally when in motion but when i try putting the gear in park, it doesnt enter park until i tap the gear stick several times. When i put into drive, it enters into drive but the 'D' light wouldn't turn on until i tap the stick. i think it has to do with something under the gear stick. Honda experts, pls what do i need to do?

From the physical inspection nothing is out of place.. the tyres moves freely when I drive/throttle... I will go for scan as stated... Thanks and God Bless You

Alryt boss... Kindly post scan result once U av dem

Goodevening Guru's and enthusiasts...so I just bought a c300 2015 benz some 3-4 weeks ago...serviced it with Mobil 1 and only a couple of days back "check oil at next refuel" pops up after about 10-20minutes drive...I click ok and it disappears only to reappear on the next drive.


Today I realized the car jerked from D4-D5 shifts. Biko una blother need help b4 these Abuja Mechanics finish me biko

Go for a scan first, as for the oil level, the oil switch might be bad.

Good morning. My VSC, Brake, trac off, ABS light came on during the weekend and the tyre pressure light keeps on flashing. I explained to my mech that my brake gets very hot and he said its the caliper, yesterday he fixed it and the lights disappeared except for vsc and trac off. This morning, the lights came back on. Also he removed my radiator to fix a leak and removed battery to clean the terminal, now check engine light is on. Although the check rngine light wasn't on previously. What could be the cause please?

Morning boss. Very sorry for late reply.
Kindly check your Temperature sensor. Sometimes they fail and the ecu is unable to determine d state of d Engine if its cold or hot. Also check its wiring too.
Also check your idle air control system. It might be stuck.
If possible pls scan the vehicle. Certain sensors might have failed which might be causing this poor engine performance at cold start up.

Check your shift stick, the park neutral switch, and connectors to the gear system. Something is failing. I have a feeling its a switch or its wiring.

Chief like Billiebaba talk. Abeg scan that car. Nob 5hose cheap. Scanners o. Find a competent tech that can help you scan all the systems on that vehicle.
Also there shld be a way to check the oil level. Confirm the oil is properly guaged.
Also pls try contact AutoElectng on nairaland here. he is based in Abuja. I believe he will get the issue sorted for you professionally...

Morning sir. Pls kindly confirm if the brakes dont get hot any longer.
Also for the ABS, TRAC AND VSC, IF THE PROBLEM HAS BEEN FIXED, YOU MIGHT HAVE TO ERASE USING A SCAN TOOL. THING IS, ALL THIS SYSTEMS WORK TOGETHER.IF THERE IS A FAULT IN ONE, IT WILL TRIGGER THE OTHER LIGHTS. FOR EXAMPLE A FAULTY WHEEL SPEED SENSOR WILL CAUSE ALL THOSE LIGHTS TO COME ON EVEN EVAP LEAK will trigger those lights.
So a simple scan will let you know if there is a fault code stored, or if the issue has been fixed. In that case you'll just clear the code.
For the check engine light, scan the engine management system. The fault code stored will tell you what you need to fix.

welcome sir

AutoMoTech:

Please what do you mean by fuel drain?
Do you mean your vehicle consumes more fuel?
Or you notice fuel leak from the vehicle?
Pls kindly clarify... Thanks

As regards, pls be careful how you go through flood. If its possible to avoid it by taking a longer route pls do. internal combustion engines do not like flood. If water gets into areas its not supposed to get to, it wil cause a huge damage and cost of fixing will be high. Esp parts that are located in the lower part of the vehicle like starter motor, compressor, PS pump (in some vehicles), excess water or dirt can reduce the performance of your radiator, condenser and the fans.

yes my car consumes more fuel now than usual by 50%

nonhuman:

Chief.... The fuel filter wouldn't cause higher fuel consumption. Rather it will cause a restriction to fuel supply.
Your issue resides somewhere else.
Leaky exhaust, bad O2 sensors, faulty injectors, non-recommended fuel pump (pumping at higher pressure than required), faulty fuel regulator if there is one, vacuum leak, faulty MAF/MAP sensor etc. So many things can cause this high fuel consumption. Pls get in touch with a competent tech to help diagnose this issue sir...

I bought a tokubo Toyota Camry 2003 about 4 months ago, but I notice that the fuel consumptions seems to be on the high side.
I use about 13liters over 60km drive daily. Mixed of city and highway driving.
Attach is the history of my fuel usage. Found this application online and use it to monitor my fuel usage.
Please is this normal.
The consumption is measured in Kilometer/ litre.
From what I checked online (28mpg- 35mpg) the consumption shouldnt be DAT high.
Please what could b the problem

Chief. If i say I understand that picture ehn. Na lie i lie.
What i'll advice is this.
1. Write down your odometer just before refill.
2. Refill your tank to full tank.
3. drive the vehicle normally till that low fuel light comes on.
4. Note your odometer
5. Refill again
6. Drive till light comes on.
7. Note your odometer reading.



So atleast we'll have 2 test results to work with.
That way we can get an idea of your mpg. Though not actual but close to it.

There is also anoda method i came across. Lemme see if i'll see it

Converting that to MPG, my usage is abt 13-14MPG.

Wow... Dts half of d official figure...
Well... You will need to get your vehicle diagnosed to pin point the cause of this excessively high fuel consumption.
Focus on the O2 sensor inputs, ECT input, check for vacuum leaks, etc...

Hello boss, pls where and how can I get a PC based oscilloscope. Thanks in advance sir

please I need expert opinion. my Mitsubishi Chariot (GDI) 1998 suddenly stopped after a sound while on motion. Called my mechanic who informed me that the Timing belt has cut and that I have to buy a new engine. please is this in line because the price he's quoting for a tokunbo engine don weak me

If its true your timing belt cut. It doesn't necessarily mean you will buy a new engine. The valves will likely bend. He need to inspect it first to ascertain the extent of the damage. Before he advice.

morning guys

Good Morning Guru,

I just got a 2004 Matrix about a week about. The first scan code i observed was P0505
After my mechanic check the did servicing of the car with Mobil 1 synthetic , More code came out and the car engine performance is not smooth even after servicing the nozzle.
Below are the codes observed initially;
P0505
P0301
P0302
P0303
P0304

This also came out later in pending fault
P0171
P0133
P0451

Please what might be the issue for this numerous codes all at what
Your detailed reply will be appreciated.

The ones initially, observed is a misfire code for all cylinders. P0505 is an Idle Air Control code, your car might have a rough idle or stall, just have it checked,it is located in the throttle body, it might be clogged. The ones you observed after maybe has a result of faulty or clogged MAF sensor deceiving the PCM to run the engine lean, or faulty O2 sensor not feeding back correctly, there by continuously running the engine lean. Alot of variables not surfacing in the fault codes might need to be checked as well.

In addition to Billiebaba's diagnosis
First things to do
1. Diagnose your O2 sensor and its circuitry.
"P0133 indicates the ECM senses that the O2 Sensor is not changing its voltage output quickly enough to the changing air-fuel ratio. Hence why the P0133 trouble code definition is O2 sensor circuit “slow response” because the circuit is not reacting quickly enough." You can look this up online.
This could be the cause of the lean condition.
If the circuit is good. Change the sensor. Monitor the o2 sensor readings then see how the PCM responds.
2. P0451 TOYOTA - EVAP System Pressure Sensor Range/Performance.
Check your EVAP system. Ensure there are no leaks on the hoses, make sure the solenoids are not stuck closed, open or partially closed/open.
3. Once the above have been done... And the misfires are still present, then we proceed to diagnose the cause of the misfires.
