ok so here is the deal, i was drivng around and my check engine light went on, i had the computer with me so i checked it out, it was an injector circuit malfunction on cylinder 2. i checked the plugs and they are all working, i check spark and i have good spark. than i changed out the injectors and work for a day, now it is back. basicly what is happening is....

when i am trying to shift lightly in low RPMs the car sputters, than i hit about 3k and the car takes off, i dont know what else to try anything would help

Sounds like a spark problem to me. How did you check for spark?
