ECM- I'm thinking I'll hold on to it as a spare, it seems they have some problems occasionally.

Exhaust- I think every Chevy truck in my home town has a performance muffler on it, I just couldn't believe it would be my problem (plus a quick chat with my favorite muffler shop that went like this- "blah, blah, blah" (me explaining problem), they said (and I quote) "what a load of *****, look for something else". Gotta love a guy that gets to the point!

As I searched the 'net for answers I found tons of posts in several forums dealing with this kind of problem but I had trouble finding specific testing info and what were good test results and bad test results. So I have tried to be as complete as possible with my descriptions of the problem and the things that were tried in the attempt to figure it out, hoping that it will help out the next guy who has a similar bug.

Thanks again guys!
