I was at a track on Saturday and around 6-7 RPM the car was just a little choppy while under full acceleration. It was like the car was struggling to get fuel for a split second. I would floor it, holding the pedal to the floor and at about 6 or 7 rpm it whould hesitate for a second and then keep going. Most of the time, it was going into or during high G turns. Every once in a while it would do it in a straight line as well. It was always in 3rd or 4th gear. Some of the guys out there said that maybe its just having a problem getting fuel so try going on a full tank of gas next run. I did, and it still did the same thing. No warning lights, overheating, or anything i can see or hear that looks strange. Anyone had this happen before? or know what it might be?
