Engine Performance problem
2000 Pontiac Grand Am 6 cyl Front Wheel Drive Automatic 118000 miles
When accelerating the car hesitates. This occurs at any time of day, doesn't matter if the engine is cold of hot, 1st thing in the morning and after work. Doesn't matter if I'm driving 20 or 60 mph.
When I press the gas it hesitates and bucks, especially on inclines.
The plugs and wires have been replaced. What could it be? I've been told it's not the torque converter or the transmission. I've also been told it's the harmonic balancer.
What else could be causing this?
