Persistant Undiagnosable Miss

Okay- After over a week later the tech I brought my truck to has finally found the problem- it appears that the ignitor module was failing at higher RPMs and he also mentioned that the miss was still occuring with the MAF disconnected, because the engine was running rich it masked the problem. Thank you for you support and suggestions.

 

Been going through what sounds like the same issues you were here. Wanted to follow up and see if the problem never returned and the ICM was in fact the final fix to the problem.

Thanks
