Hey gang, Been away on vacation and business. So here's the latest findings. I had the intermittent 'click' while attempting to start the engine so pulled the starter and replaced the eroded contacts. During this time, the + cable was removed from the battery so the ECU got reset. When starting it afterwards, the engine ran so smooth with absolutely no signs of a misfire until..... it got fully warmed up and then slowly, the misfires started to occur again. So... I can only assume that this is a sensor related problem. Now, of course there are no codes being thrown. Oh.. one more nugget. It seems that once the ECU gets a good dose of engine sensor input, it'll do the misfire quickly upon starting, cold or warm. Thoughts? <img src="/forums/images/graemlins/confused.gif" alt="" />
