I know this isnt an Intrepid or even a DC, but I thought you people are pretty car-intelligent and this is a pretty general engine problem, I'd think. Anyways, the '03 Blazer(90k mi) revs into the 2-3,000RPMs when you start to accelerate and takes a second to actually accelerate and shift. At higher speeds it seems to act normally. Someone said it was the carberator(guessing they actually meant the EFI), but I don't know anything about this. Any help on this matter?
