So I went to the track the other night which was 1.5hr away. The car drove up there fine, did well on the runs, never came close to overheating or anything out of the normal. Then about a quarter to the way home it started bucking at low rpms. Around 2300 it would clear up and be like normal and have great power like normal. I also noticed that when it bucked the exhaust note changed and the boost gauge shook with the bucking. I then took the car out today and the car didn't seem to be nearly as bad but about 15-20mins into the ride the car started bucking just as bad as it did before. Any ideas?mafs or something worse? I should also add that the car idles fine revs fine, if I even hold the rev at around 2grand it won't buck but in gears it does.
