Hey guys, was wondering if anyone could shed some light on a rather concerning issue I have with my 98 GT. When the car up-shifts to 4th gear it locks at 1500 rpm and stays there unless I take my foot off the gas and re-apply (thus obviously downshifting to 3rd). I've had some people tell me that it might be the TPS but I disagree because would this not cause problems in all gears? Thanks!
