jcbt Posted March 12, 2015 Share Posted March 12, 2015 Misfires are usually coil packs or clips and sometimes spark plugs. Quote Link to comment Share on other sites More sharing options...
themodifiedkid Posted March 12, 2015 Share Posted March 12, 2015 If you have changed coil pack clips and it's worse, check you have wired them up correctly Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted March 12, 2015 Share Posted March 12, 2015 The title had me slightly concerned! anyway have you any mods? Quote Link to comment Share on other sites More sharing options...
Nic Posted March 12, 2015 Share Posted March 12, 2015 Has this started, was the car running fine before? What mods do you have, what boost are you running and what spark plugs do you have fitted? We need a lot more information. Quote Link to comment Share on other sites More sharing options...
