Hey there guys. New to the forums and I've got a Blue 02 Grand Marquis. Well, actually its dad's car but I drive it often enough to take some care of it . I've got a misfiring problem and my friend hooked up his scanner reading a intermittent cylinder #4 misfire. Since the car has a coil on plug ignition style I figured to just change out the plugs and cross me fingers.

Bought the plugs today, regular platinum Autolites. The guy at checkers told me the gap clearance is .054. I come to guys to ask because I don't have a repair manual yet and would like to get this misfiring gone asap!

Would someone be so kind as to telling me the gap clearances for an 2002 Grad Marquis?

Much Aloha,
K
