I got my car back today, my mechanic ran a pruduct called Virt (basically a german version of seafoam) through my intake and gas tank to clean out any dirt in the car. Well I got my car back, and the electrical problem I had seemed to dissappear. Im almost home, the car shuts off on me. I restart immediately, and then it runs fine, but everytime Im at a stop light or in neutral the revs would jump from 1000 to 1700 and it would just keep doing that. Do I just need to do a Throttle body adaptation? I looked at a few threads and even sites, and from what ive gathered is it simply just unplugging the battery for a few minutes and reconnecting it, or is there something else to it?

 

ya unplug the batt. athen plug it back in, turn the car to the on pos but dont start it. let it sit there for like 30 seconds to a min and then you should be fine. also check to see if you have any vac leaks

 

it could be that or your Idle control valve is screwed up[&:]

 

is your cel on or flashing when this happens?

 

What is Virt? i have never heard that before? and was there something wrong with your car before you brought it in?

 

a side note to this topic... my car idles at around 1300 give or take a 100or so rpms, ans then it will srop to 800 then back up to about 1400... what could be causing this and where is the idle control valve located.

 

ok STOP

you have to get a VAG tool or know someone with a VAG tool
that is the ONLY way!!!!!, i have already ran into a similar problem after replacing the battery

i know its major gayness but you have to have the tool
and follow both throttle procedures found here:

It wasn't idling at 1700, the gas pedal was actually moving on its own revving the car up to 1700 and then back to 1000. Over and over again.
