Ekona Posted July 27, 2016 Share Posted July 27, 2016 Bet he's got the coil packs plugged in incorrectly. Quote Link to comment Share on other sites More sharing options...
Ekona Posted July 27, 2016 Share Posted July 27, 2016 Or, and this is a guess, it might be the MAF. Quote Link to comment Share on other sites More sharing options...
TT350 Posted July 27, 2016 Share Posted July 27, 2016 Mine had this EXACT ailment. A coil pack was buggered. Quote Link to comment Share on other sites More sharing options...
