Dear all, I recently noticed a low pitched winning noise in the transmission a few week ago. I checked the fluid level and condition, all was okay. I did a 500km Journey recently, the next day, I noticed a hard thud while shifting to drive. Now the car jerks intermittently while driving. Pls help. I am in a remote location so can't scan the car. My potable scanner shows that knock sensors on both banks are bad. Gazzuzz and co...pls help me.

There seems to be a mechanical issue going on with your transmission( with respect to the whine). Did you recently perform an ATF fliud change?
Knock sensor can definitely cause transmission shifting concerns. So I strongly suggest you fix that first. Most likely rats might have eaten up the wires?
Please note that accessing the knock sensors is not DIY for most people.

I was in a place where two men where arguing about this . Pls, let’s here from you guys.

Exactly what years are you talking about sir?
BTW the Toyota Corolla is the heavier car, with a higher engine displacement, so it is expected to be less economical to run than the KIA Rio.
The KIA Rio is in the same league as the Toyota Yaris.

You can visit my thread for more comparrisms and reviews:https://www.nairaland.com/4467246/motor-guru-here-ask-questions

In layman's terms, this codes implies any of the following:
1. Too little fuel going into the combustion chambers to achieve a stoicometric ratio
2. Too much air( unmetered) going into the combustion chamber to achieve a stoicometric ratio
Note that the stoixometrix ratio I am talking about is the quantity of air required to mix a specific quantity of fuel to achieve combustion, which is about14.7 parts of air to 1 part of fuel.

Now regarding your case, for point 1 I advise you check your fuel filter condition if it is severely restricted. This can ultimately kill your fuel pump BTW. Dirt in the system can also cause a restriction to your fuel injectors(nozzles).

For point 2, since your car uses a MAF, check all hoses and air connections AFTER the MAF. Any unmetered air will have to be compensated for by the ECU by allowing more fuel to be dumped into the combustion chamber, causing fuel trims of over 25%. Your MAF sensor should also be inspected for dirt , as dirt can cause inaccurate reading, causing a false code to be thrown.

Finally I would also suggest you check your exhaust system for leaks especially at areas before the air/fuel ratio sensor. Leaks will cause the sensors to throw false error codes too.

Hey MotoGuru.. Am considering purchasing a Mazda product. I am also considering purchasing a Nigerian Used and my Budget is 700k. Which of these Mazda products you think will be OK for me in terms of Cheap parts, No too much wahala and low fuel consumption.

Okay sir. Thanks for this and I will surely get back to you.

The pleasure is all mine.

b0y:
Thanks sir, I meant the latter - ABS kicking in on its own. It will occur whenever I'm in motion at any speed.

Kindly check if the ABS sensors are all installed properly. Did you do any work on your hubs recently ? Or better still look for anyone that has a scanner that can scan ABS systems and post codes here.

b0y:
Good day,

What could cause a car to intermittently engage (sort of) the brakes on its own will on low/moderately high speed? I use an acura tsx and ive practically checked everything with a mechanic to no avail.

When you mean brake do you mean with the engine still running or does the engine shut off when this happens? Or do you mean the brakes(ABS) kicking in own its own?
You may need to clarify sir.

Samony:
I have not scanned it yet. Will do that and get back to you. Thanks

Has vehicle been scanned yet? Please post here if done already ( I.e if issue has still not yet been resolved)

fidinwala:
please what is the best Engine Oil for Pontiac Vibe All Wheel Drive

Sorry this is coming late but:
Is the car recently purchased? If yes, is there any documented history as regards previous oil changes?

The reCommended oil viscosity for your car is 5w-30. Fully synthetic is best. Mileage and condition of vehicle would be a factor if you might experience issues such as engine oil shortage and whatnot.

Seasons greetings my automotive friends!

For a V6 it might just fit with very very little room for engine accessories (for the M112 engine)Note that there may be a little structural modification involved to the chassis rail).

For a v8 it will definitely involve significant structural modification on the chassis rail and strut tower.

the w201 chassis was never designed for a v-configured engine

GAZZUZZ:
Uncle welcome back o!

Thank you sir!

Do not buy an 18 year old car to replace a 15 year old car, get something newer and maybe smaller...
There's a Yoruba adage that comes to my mind, due to the circumstances surrounding the purchase, it says: "what you said the head of the home shouldn't hear about, he's the one that will settle it"
Because if the deal doesn't go as planned or other things start coming up....

Newer is better( of course), but i would focus more on the condition of the vehicle than the age, given the budget and purpose of vehicle. I have ridden in 1999 Camry's that were far better in condition than 2012 ones

Samony:
Hello MotorGuru, I hope u are doing great. Refer my previous post. I have changed both the gear oil and filter of my 03 corolla and it is still having same issue.

Here is my complain

(Well-done Motor Guru..Please there is something I started noticing in my car. Sometimes when i engage my gear, especially on reverse, the car won't move. then if I throttle slowly, it still don't move until after some seconds before it picks. I took it to my mechanic, he change the gear oil and wash the filter. after a while it started again. pls what could be the problem?)

Wow sorry for the incovience. Have you scanned the car for trouble codes? if you have not, please do.
If you have already and you have no codes, then i am afraid the valve-body of your gearbox has been compromised.
This usually requires change of complete gearbox for peace of mind, But if it ever comes to this, please contact the moniker [b]Kashif [/b]on this forum before you make any decision.

PaChukwudi44:
shiooooo Bros when exactly did this happen? In your dreams perhaps.

I don't know the constitution you are using perhaps the futan jalon constitution but here in Nigeria the constitution vests control of all the lands in a state under the state Government and not federal government

Very true.

Whatever I do with my life is not your business.

Noted.

sarahade:
Who be this one? You greedy fools how many men allow their women to be independent abi how many of you will agree to sit at home to clean and care for your children.

Confused beings you want a loyal independent self made woman that will take care of you and the children and what do you bring to the marriage nothing but your tiny penis.

Women wise up a man that is not ready to share responsibility both financially and at home is not worth marrying find yourself a sperm donor and live your life
Marriage is not a criteria to make heaven.

Your opinion about men is quite frightening.
I think it will be in your best interest not to marry ( a man)

The front passenger's door tho....
