#1 of 1 I'm going nuts.... by caseysmydog Oct 25, 2008 (3:44 pm)
98 Regal 3800 skipping. Code was P0304 (misfire cy 4). Replaced plugs/wires/one injector/mas sensor. Still skipped. Cleaned EGR valve and PCV valve. Then got P0300, random misfire. Took to top notch garage. $300 later, they said it was a bad plug. On way home from garage, car skipped under load (going up a bridge) and I heard a pop noise. Anyone got any idea what's going on? Many thanks, David
