2002 Pontiac Grand Prix Q&A
2002 Pontiac Grand Prix Question: What is the problem?
I have a 2002 Grand Prix GT 3.8L. Just had the upper and lower intake gaskets replaced, the valve gaskets replaced, a new radiator, and a new 4th gear shaft put in my transmission as the car was not shifting from 3rd to overdrive (this works fine now). The problem I have is that when I depress the accelerator 1/4 to 1/2 the way down (seems like the same type spot each time), the car starts to jerk and the rpms go up and down during acceleration. Once I push the accelerator more to get past this oint, the car accelerates fine. This mostly happens when going up a hill and trying to maintain power going up the hill or, when accelerating slowly. When I punch it, no issues. - lancerecruit
