I've corolla xli 2012 having some RPm issuess, help needed,
Well whenever i start my car, RPm goes under 1000x
And car is vibrating so much, it's really annoying, Car vibrates only on neutral, rpm stucks at 500 or 600,
And while driving it works fine,
I totally understand your frustration! as i too work on my car my self.and have to research problems i encounter.. after looking at your work list the only thing that comes to my mind is the resetting of your ecu( have you tried that) look it up on how to reset the ecu! or the simple hard reset remove battery terminals overnight . .another thing that i just realized! does your car have a catalytic converter? it might need cleaning!
Done the ecu resetting about a thousand time the car remains alright for around 10 minutes phir voi masla.catalytic melt huwa WA tha mene remove kerwa diya.cng pichle owner ne lagai hui thi ab ni hai.throttle cng ki waja se to change ki hai I have cleaned idle valve control aswell I didnt saw any carbon deposits.another thing I was going through this idle problem on YouTube a video said to remove the manifold and clean it thoroughly as it has carbon and my car does have carbon when I remove the tb.shouuld I do this?
did you replace the converter or remove the whole unit?
what happened to the emission sensor on it?
since i'm not a qualified engineer id suggest talking to Xulfiqar the man has exceptional knowledge (i read his posts if im stumped regarding any DIY work on my car)
Please check maf sensor at the top of air filter box. There will be two screws, and check if the rubber seal is broken or not, if its broken or missing than that's the issue.
I faced this issue in my 2006 gli for like 10k and in the end came to know some toyota service guy forgot to put a rubber seal with maf sensor.
i think have to live with it .......
similar issue is in corolla 2010 ...
rpm drop when ever electrical equipment is operated eg headlights turned on , blower turned on etc
and while traveling if gear is put to neutral rpm drop to 500 - 600 with vibration .
some one recommended to reprogram ecu from toyota may solve issue ....
never went for it
A friend of mine has 2015 corolla same issue which u quoted,he has and I have.i cant figure out whats the issue this problem is damn irritating I replaced my car's dynamo and fuel pump,fuel filter aswell regarding this issue but still remains.but haan me jab ecu ko battery remove ker k reset kerta hun to the car remains Allright for a drive of 3-5kms phir auqaat pe aajati hai lol
I opened the manifold today and cleaned it 2.5 litre of petrol consumed and the petrol which was coming out was still black it hadAlot of carbon in it besides all of these thing the issue didnt resolve lol still the has the rpm issue lol
@ burhanzaki! bhai if you have done everything and its still not working. just for the heck of it try two last thing!!! cant hurt. clean the carbon sensor that was in the catalytic converter.. and lastly check all the large capacitors in the engine fuse box and the fuse box behind the glove compartment...
