-Alex- Posted December 10, 2011 Report Share Posted December 10, 2011 Throwing any codes? Cam position sensor? Quote Link to comment Share on other sites More sharing options...
Green Bastard Posted December 10, 2011 Report Share Posted December 10, 2011 i would say sensor or timing possibly being off, im sure theres a way to time the ignition Quote Link to comment Share on other sites More sharing options...

PRD2BDF Posted December 10, 2011 Report Share Posted December 10, 2011 Is it leaking coolant or some kind of liquid into the combustion chamber? When I power-washed my engine bay one day, some water got into the inner workings and caused a misfire. Quote Link to comment Share on other sites More sharing options...
im faster Posted December 10, 2011 Author Report Share Posted December 10, 2011 Nope.. its been going on for months.. he replaced the coil last year and it fixed it until a few months ago.. I then replaced all the above.. and it still is misfiring. Quote Link to comment Share on other sites More sharing options...
DavidBaustert Posted December 10, 2011 Report Share Posted December 10, 2011 Spark plugs? Quote Link to comment Share on other sites More sharing options...
im faster Posted December 10, 2011 Author Report Share Posted December 10, 2011 i just put brand new iridium plugs in Quote Link to comment Share on other sites More sharing options...
PRD2BDF Posted December 10, 2011 Report Share Posted December 10, 2011 A quick (30 sec) Google search suggest that the fuel system could be blocked causing the engine to run lean and misfire. Maybe check the A/F to see if it's running lean? Quote Link to comment Share on other sites More sharing options...
Wonderboy Posted December 10, 2011 Report Share Posted December 10, 2011 Have you checked to see if you actually have a spark at the coil or plug? Have you checked to see if you have a proper signal at the injector? Is it at idle, under load, or all the time? Any other codes? Quote Link to comment Share on other sites More sharing options...
SinisterSS Posted December 10, 2011 Report Share Posted December 10, 2011 are you using factory parts or aftermarket? instead of replacing the coil(s) you should have swapped the known bad one with another cylinder to see if the misfire followed, if so then replace the coil, if nothing changed then you could have an open wire somewhere in the circuit, or a bad PCM Quote Link to comment Share on other sites More sharing options...
Crossle Posted December 13, 2011 Report Share Posted December 13, 2011 are you using factory parts or aftermarket? instead of replacing the coil(s) you should have swapped the known bad one with another cylinder to see if the misfire followed, if so then replace the coil, if nothing changed then you could have an open wire somewhere in the circuit, or a bad PCM Diagnose before hanging parts. Saves people money and you a headache. Quote Link to comment Share on other sites More sharing options...
