I have a 94 Grand Prix, with a 3100. It has 150k miles on it. It was running fine, and the wife calls me and tell me the car is shaking...
I get home, and the exhaust sounds like a misfire. My plugs, and wires are 1 year 3 months old, 15k miles old. The exhaust doesn't smell really rich, and I have no SES light. (I couldn't check it anyway, it's the ODBI/II mutt). So, what should I look for? Should I take the time to remove the plugs and wires and check them out? or should I focus on the ignition coils?
