well first off, i just installed my tvs harrop kit a few days ago. running stock pulley (3.15) and 80# injectors. At first it had a jumpy idle and was idling wayyy rich. I fixed that by adjusting the short pulse. Well i just came back from a run and at cruising speed my afr jumps from like 14.3-15.3. When i slightly accelerate from a cruising speed it still sits around those numbers, seems like even getting richer. I keep getting a P0172 Bank 1 Rich, and a misfire code. I fixed the misfire by gaping the plugs at 35. Any ideas? I've been at this for a few days now and really need some help!!
