I was driving when loss power and motor felt like it was jumping. Engine light came on and off. The EPC light came on also. Diagnose that needs coils replaced and ground wire.

Check engine light came on, and a mechanic determined the coils should be replaced. However, they had already been replaced at some point because of a recall. I had the mechanic turn off the CE light, and after driving it 200 miles, it never has come back on.

my car started up fine and when i went to take off i got to the end of the street let the clutch out while in nuetral and my car stalled and when i tried to turn it over it wouldn't start. my friend who is a mechanic figured out it is the spark plug wires and we replaced the distibuter cap plugs wires and everything seems to be back to normal :)))

Whenever I stepped on the gas quickly the car started jumping. Engine light came on and off and if I didn't let up the EPC light would come on. The problem continued to get worse and worse until anytime I stepped on the gas it would sputter. Had to replace the ignition coil replaced and ground wire. After one dealer told me it only needed an injector cleaning service.
