1998 Grand Prix 3.8 L "Cyl 6 Misfire Detected"
I have a 1998 Grand Prix with a 3.8 L engine with 251,000 miles. It is running rough at idle (especially when warm) and the check engine light comes on after a minute or so of rough idling. The code that comes up is "Cyl 6 Misfire Detected". I just installed new AC Delco plugs and wires and I am still having the same issues. Any suggestions?
