Q: I have a 1995 Grand Marquis and I took it to Autozone and they read the codes and said that cylinder 2 and 5 were misfiring. I already replaced the spark plugs, should I replace the spark plug wires or the coil pack first? Has anyone else had this problem?
A: Check for moisture in the boot of the spark plug wire at the coil pack. I had the same problem with moisture build up. New plug wires if you have more the 75 k on the odometer.
