heres my problem; my car accelerates fine if im easy on the pedal. but if i smash the pedal completely down, the car bogs hard and then accelerates normally. i have done new plugs, wires, cap & rotor, catalytic converter, made sure timing is good, next will be fuel filter and o2 sensor. i have been looking through several sites archives and people have mentioned the tps. i am not throwing any codes, so i figured my tps is fine. i have a dohc zc with a pg7 ecu, anyone have any suggestions or been through something similar? i need to get my car emissioned, but i want to make sure its running right before i try. thanks alot.
