Had a bit of a mishap on a rather long drive from Montana to Mich. #4 plug vibrated lose, burned the electrode off and obviously the engine began running like crap. Checked the engine, found and replaced the plug, still missing. Test of coil pack showed it was bad, so replaced it, other cylinders (1 and 4 were missing in diag) 1 is now firing fine, but 4 still has a miss. Any thoughts. New wires and plugs (before leaving trip) i replaced all plugs when I replaced the coil pack. Wires check out with about 6000 ohms resistance. Could I have screwed up a valve in #4 when plug burned up? Check engine light flashing once car is hot. any help appreciated.
