If i accelerate my car like if i was to overtake another vehicle and just let off of the throttle, the rpm's come down and the engine shuts off while still moving. My scanmaster readings are within spec. Any ideas?
 
Also, the car is basically stock. It has a turbotweak chip purchased recently from eric marshall. I did do a search on here but did not find anything.
 
IAC controls air into the engine when you let off the throttle. So either its not set correctly or the IAC motor is dirty. Could even be a chip issue.
 
Sounds like DFCO. Decell Fuel Cut Off.

Eric may be able to tune this out. I would get with him.

Mine would occasionally do this also. My Iac # was way too high. I adjusted down under 20, and it has been fine ever since.
 
Then he prolly has it shut off already.

Like suggested maybe the iac could use some adjustment. Do you have a scanmaster?

Rick
 
yes, the scanmaster iac reading is 15-16 at idle when at operating temperature. Should i get it closer to 0?
 
Yeah but if (IAC) its sticking in the hole or has issue.. it will shut the car off ;)
 
Well, it seems you guys came through again. I cleaned the IAC, while i was at it, i cleaned the throttle body and blade. I set the IAC at 05-06 and it seems to have stopped the stalling. I hope this was the problem. I REALLY appreciate all of you that helped me out here.
