Car is a 1995 GT. Full exhaust and cold air intake have been on it for about a year now. Car still has less than 100k miles on the clock. Engine is stock, tune is stock. Car has 3.73's and 315's out back. Anyways, while accelerating, as soon as it reaches 2k on the tach, the car hesitates. There is no backfire associated with this condition. It can be revved past 2000rpm while not in gear and the car doesn't hiccup/hesitate. So it only happens while in gear, driving with/under load. Cleaned the MAF. Made sure everything is hooked up like it should be. Filled the tank with some premium fuel. And added some injector cleaner and water remover just to be safe. The car accelerates fine past 2k. No other symptoms exist. Just a small hesitation at 2000 rpm's, and I am not sure what it is. From what I have heard, it could be a faulty MAF or O2 sensors, or both. Also thinking it could be related to the TPS. Not sure what it is, but I don't like it. Any help would be greatly appreciated.
