well I read the code from a generic lil obd scanner lying around the garage I was at.

the RPM idle actually smoothed out after that day, I'm thinkin' now it was just the ECU getting used to the new spark plugs. As soon as I get my hands on a VAG, I'm gonna do the TBA for a good measure too.

Thanks once again for all the prompt responses, u guys are the best.

 

Glad it's fixed. Thanks for the update.

 

you should still clean out your throttle body.

 

Naah, thats defintely the icm,mine did the same exact thing.

 

its really late, and im reading that saying "what?!?" in my head, so what was that you were sayin?

 

Im saying my car did the same thing, would act like it was fixed,(new plugs) then shortly after that it would begin to do the same, it turned out it was my ignition control module or icm.
