Local High school kid has a 97-03 GTP with no flow mods and what looks to be a 3.2 pulley Lately the car has been breaking the spark plug in cyl 3. It has done this three times so far. I was thinking detonation at the worst forum or maybe rod play, crank play, or a worn out wrist pin? And what are the chances of the spark plug debris going out the exhaust?
