92 mtx 3.2l missfire

[angstrom89]

The car is miss firing. New spark plugs, wires, coil, crank sensor and cam sensor. Got a code 542 put diffrent ccrm in does the same tried a dis off a car that ran good, cleaned up the conections same thing havent tried pcm i could but i dought it is the problem. And the car is backfiring as well. Has this issue once before didnt back fire last time and one of the pressure plate stapes broke so it just vibarated the motor and felt like a missfire. If any one has sugestions let me know.

add to last post

took the car in right before and got the car aligned right after the car stated with miss fire should have nothing to do with that. And the car has a light weight fly wheel and when pushing in clutch when coming up to light car revs up and down rappidly and when shifting it would rev up slightly under normal driving.

Do you trust the people test driving your car after working on it?

Not really I guess I wish I had my own alignment rack. Espeshaly with that clutch 3 puck caramic on one side and Kevlar on the other for a little softer engagement.

double check the spark plug wire routing - many books show it incorrectly, which of course results in a miss after you change plugs and wires.

the missfire went away. but it needs head gaskets might just rebuild a motor for it.
