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 :)))

I don't know what is wrong. I have the check engine light on. A tech at a mechanic shop told me its a misfire at cylinder #5. I need to be shown how to change whatever I need to change to get this fixed myself. It is too much money to have mechanics do the job. I also have the ABS light going on and telling me that ABS failure/failed in the dashboard digital display.

Engine would misfire whenever there was heavy moisture in the air. (i.e. rain/humidity). I replaced the coil with a German built aftermarket product (did not want to go stock since it was the stock unit that failed) and I have not had any problems since. The car starts up without delay no matter the weather and no longer misfires. I also put in new plugs and wires just to cover my bases.
