Ok Lately at 1500-2000rpm my car hesitates and stutters. Soon as it gets past 2k it runs good. It was doing this last week and a put in a new ignition module and I thought it was fixed but now its back. Also the car wont do it at all or not as bad when its cold. Soon as it warms up it does tho. Also it doesnt do it at all throttle positions.

 

Ok I think it was my CTS. I replaced it and drove it alittle and the problem and hesitation is gone. My CTS was screwed up. After my intake install i managed to smash the sensor and break it and just stuck the harness in there anyways......should have known it would screw it up

 

ok replacing the CTS helped out alot but I'm still having the problem alittle..could it be the throttle positioning sensor maybe?
