Ok i have a VIII with a Aem intake, TBE, 272 cams and gears, MBC 21psi, i had the car tuned and it was working fine. I had the clutch replaced by the dealership now it does not want to start right away i have to push on the gas and keep the rpms up on it for about 10 min then it will work fine. And it stalls sometimes when i stop at a light or turn on the AC. Now i think it is because i disconnected the battery wich i know that resests the ECU or could be something the dealership did maybe. But i waited a couple of days to see if the ECU just needed a couple of days to reset itself. So would that make the tune go away? Here are the things it also might be need to know what u guys think. I did search for this too and here is what i came up with

ECU needs to be retuned because of disconected battery
vacume leak have not checked for this yet
Stealership dissconected something and did not reconect it
Bad stock injetors doubt it or they are leaking


Not sure what else it could be thanks for any help guys

 

Sounds like they might have flashed over your tune, or you have a HUGE leak.

 

if the battery is disconnected the car is supposed to idle for about 10 min. with all acc off. then drive for about 30. it sounds like a IAC problem . just pull the neg. cable for a few min do the above and see if it idles right.

 

Maybe the deal reflashed the computer with some update for whatever reason and erased your tune, do you have any way of checking to see your map?

 

No i dont have any way to do that. But with all the searching i have done it seems a lot of us have this problem. But it seems no one has found a fix for it yet. I am thinking i need to put the stock intake back on maybe its the MAF
