James Posted November 6, 2015 Share Posted November 6, 2015 Not sure if yours still has the ignition amplifier if so it could be that. Also, I've even seen reports before of misfires caused by boost pipes that have become disconnected. Quote Link to comment Share on other sites More sharing options...
Arronbill10 Posted November 8, 2015 Author Share Posted November 8, 2015 Thanks I will trace all boost pipes for leaks. Mine doesn't have the ignition amplifier. Quote Link to comment Share on other sites More sharing options...
James Posted November 9, 2015 Share Posted November 9, 2015 Any luck on the boost pipes? Quote Link to comment Share on other sites More sharing options...
Arronbill10 Posted November 9, 2015 Author Share Posted November 9, 2015 Have no leaks on boost pipes but I did notice the wiring to the egt sensor has snapped. But from what I can see on the turbo it looks like it has been blanked ? Confused Quote Link to comment Share on other sites More sharing options...
James Posted November 10, 2015 Share Posted November 10, 2015 Hmmm I must say I'm pretty stumped it sounds like you have tried everything obvious! Quote Link to comment Share on other sites More sharing options...
