Hey guys, I had an issue with my car stalling intermittently and idling rough.(also ran a bit rough) I checked and it pulled codes for cam and crank sensor. I replaced both of those along with the MAP sensor just to be safe. We also checked for boost and vacuum leaks and there were none. The car is still stalling every now and then when I come to a stop sign or traffic light and it's driving me nuts!!! The car does seem to be running much smoother now though. What could it be? Thanks so much and any help is greatly appreciated!

 

IAC, Tune, Boost Leak, Vac Leak, Intake Hard Pipe messing with the MAF.

Common issue. You can up the idle and ISCV settings sometimes it will help out

 

Yea, no boost leak or vac leak. (car idles at 1k) The weird thing is that after replacing all the sensors, the car runs much smoother. I guess I should take it over to Sean Ivey in New Jersey.


ps: I should mention the car was just tuned before I bought it by Kunal (aka Kunnniiizee) He is supposed to be very good.

 

Yea not doubting your tune but sometimes more then WOT needs to be accounted for if the car was not doing this previously. I would prob look to possibly a bad IAC or things that can go bad/come loose.

I could help you look it over depending on where in PA you are. PM me if needed

 

you have aftermarket injectors? are thay scaled correctly?

 

does it happen when braking? do you have a VTA BOV?
