Post #4 cylinder misfire
Hello guys I need some help here.... This Has been very annoying for me lately! This only happens when the car is being "turbotimer" timed out for 2mins.(me not in the car etc.) Does not happen all the time, just more frequently. :evil:
Okay, I have replaced my spark plugs, coil pack, power transistor (oem from dealer) I also replaced the spark plug wires. (NGK brand). I also have a crank sensor at home and a cam sensor at home. But Im hoping not, to have to go that route yet... Any help or suggestings would be appreciated. Thanks guys

Did you have a 6bolt or 7bolt? Also you can tell DSMlink to ignore the misfire codes. It is probably being caused by a Cam sensor and crank sensor timing algorithm in the ECU. Theres nothing you can really do, just disable the ecu's misfire check in the MISC part of DSMlink. If you misfire, you know, and don't really need a CEL to tell you.
