RE: Im stuck here guys ...
I definitely agree with 95slvr on this one - probably opti based on your description of a slowly worsening misfire situation - if you had bad, or shorted/melted plug wires you would more than likely have a misfire and throw a code even at low rpm. You said you ran OBD and found nothing, but with a misfire like that you HAVE to be throwing at least one code. I would probably ask a GM guy in your town to hook up his Tech 2 to your car and get a proper and clear reading on whatever codes you're throwing. I've found their $4000 scanner is a lot more accurate than one you purchase at pep boys for $100.
