cruiser54 Posted July 27, 2013 Share Posted July 27, 2013 2 things come to mind. The engine control grounding system and poor signal through the C101 connector. Click on the link in my signature and read the write-ups on ground refreshing and C101 cleaning. Takes less than an hour to do both. Link to comment Share on other sites More sharing options...
