been chasing codes and finally got everything fixed to one cylindar, changed plug, then changed coil pack. still got code, saw that the coil connector wire was burned in houseing, bought new connector and replaced it. still got same code misfire. finally broke down and took it to get a "expert diagnostic". im thinking compression lose head gasket leaky valve. i get the phone call, your coil pack is bad, the fried coil wire probably messed it up he says.

could this really be the case? if so i just spent 90 bucks for a diagnostic for a problem i thought i fixed. guess its better than having to rebuild the engine.
