Thorin Posted July 2, 2006 Share Posted July 2, 2006 Plugs. Ignition based anyway I'd say. Checked distributor and leads? Link to comment Share on other sites More sharing options...

mattanna Posted July 2, 2006 Share Posted July 2, 2006 When was it serviced?, take your plugs out and look at them,if they are black and shitty there is the likely culprit, also air filter Link to comment Share on other sites More sharing options...

DamanC Posted July 3, 2006 Share Posted July 3, 2006 James - it maybe worth checking your ecu fault codes. there is a guide on here, failing that i can do it for you (takes about 5 minuites). thats if NA's log the fault codes? Link to comment Share on other sites More sharing options...
Thorin Posted July 3, 2006 Share Posted July 3, 2006 there gapped to 1.1 mm does this sound right? Yeah thats fine. Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 3, 2006 Share Posted July 3, 2006 When did you last use the nitrous? I'd get a leakdown test done in case you have done some piston damage. Did the plugs all come out looking totally the same? Link to comment Share on other sites More sharing options...
Alex Posted July 3, 2006 Share Posted July 3, 2006 Have you just valet'd it and steam cleaned the engine? Link to comment Share on other sites More sharing options...
