 M44 Rough Idle/Misfire After Spark Plug Change
Had the valve cover gasket done as when I checked the spark plugs there was some oil. Got it back an it was fine, decided to change the plugs as they may have been bad from leaking oil. Took old plugs out, some had oil on them, looked dirty over. Changed them and now has terrible idle misfire and will barely idle. No idea what happened, changed plugs again. Same symptoms. What now? |
