Car reving by itself

[topher]

i thought the tb should be between 5 and 7 degrees at idle on those engines. did you do a throttle body adaptation after you cleaned it? was it revving strangely straight away after cleaning the throttle body or has this developed since?

Yes it came after cleaning the maf and changing the battery. I didn't remove the TB at all just took the air intake pipe off and cleaned what i could get to with Wynns cleaner. ^^^

you're confusing me now.. who cleaned a maf? lol

Soon as i cleaned the TB i am sure the problems started with the idling. What was happening was the car wasnt starting right away. Taking a few times so i changed the battery (unplugged a few minutes) and the problem hasnt came back. Just the horrible idling is still here. I didnt touch the TB though and i tried cleaning the maf today( after the problem started.

Haha. Right. I cleaned the throttle body, then i am sure problem occurred. Then today i tried cleaning the MAF to see if that would fix my problem but no help.

I tried doing a TB re-align but when i type the group number in on vagcom it just says error. The TB angle is 9 though. Car is shuddering as well.

how many miles have you done since cleaning it? they can take up to 40 miles to adapt themselves, its usually more like 5-10 though. also if the problem is something EGR related it can take a few miles to ping up an incorrect flow error. what are the maf values at idle and while driving?

The first thing you touch.Then got this, will be the course. Sounds like its not your maf if that was the second thing you touched, after the problem.

also check you reconnected properly any vacuum hoses you removed. whats your engine code? on some of the N/A engines i know there's a couple under the airbox that you can pull off without realising

I'm sure i have checked all vacuum hoses, but i will check again tomorrow. Cheers
