Hey everyone I just test drove a 140k 97 gtp and I noticed under heavy acceleration it would stutter but not under light acceleration. I asked the guy about it and the dealer said that he probably ran some bad gas through it. He said he replaced the fuel pump and filter and ran fuel cleaner through it. What else could it be? There arnt any service lights on iether. Other then that I don't have any complaints. I'm getting a pretty good deal on it so if its something major then I don't wanna deal with it.
