[QUOTE=steelman223;15414639]Just bought an '04 GTO M6 about a month ago too. It had 65k on it. Pretty clean but needs some tuning. It has headers and no cats and I am not sure if it has an aftermarket cam or not. It won't shift at WOT and I am hearing that the clutch master cylinder is too small on these cars. The idle and inability to run smooth under 2k (bucking in 6th gear at 65mph) is a problem as well but I can't find a vacuum leak and I am pretty sure that the cats being gone are the cause of the DTCs. Any advice on where to go next? Does it need the cats to run good? I found a couple tuners but I don't want to find anyting else wrong yet and haven't taken it.[/QUOTE
Sounds like your car must be tuned already, have a tuner check to see if "lean cruise" is on in your computer and turn it back off...that's the bucking problem probably...also kind of sounds like you may need a skip shift eliminator kit...does it lock out the gears other than 4th under certain conditions?
