Nathan_M Posted January 1, 2017 Share Posted January 1, 2017 Sounds like air or fuel related might be worth checking the air filter is properly in place, maybe coil pack or ht leads but that would normally be noticeable most of the time you would think Quote Link to comment Share on other sites More sharing options...
