Thanks Smokensparks! Great website! cheers

Before I tackle the dealer at a higher level, I'm gonna' take it to MY mechanic. He is a GM schooled C5 specialist and worked at this dealership before going out on his own. I doubt if he'll charge me $90 per hr. for diagnostic work. I do have all the codes the dealer pulled from the DIC for comparison. :rolleyes:

Guv...
