I just got the car running last week and in between 2000 and 3500 when i am quater throttle the car studders real bad. When i give it more gas then that it is fine. Could it be that the computer has to be customed tuned for the cam, or since i am sending a throttle position sensor light. Any help would be appreciated.

 

you mean you're setting a code for the TPS? if so i think i'd try to trouble shoot it a little bit and see what it leads me. if i misunderstood you i'd scan it, check the tune up, check data stream with scanner if i had one.
