Backfire
I will try to explain this a best as I can. I have a 98 Formula A4 I have longtubes, TSP duals dumped, and no EGR. The problem I am having is when the car is in 4th and I am doing 40 to 50 and I slowly accelerate the car hesitates and backfires. The car runs great idles fine when its cold or hot. it only does it in that situation.
