I have a 2002 400i manualwith modded muffler, modded air box, carb slide mod k&N filter brand new, and a dynojet kit.
The kit calls for the dj38, but my plug shows white so I jumped up to the dj40. The problem is when it is sitting there idleing it hickups. Also When I was doing my plug check I would be running wide open shut her down and cost to a stop. When I would stop it would backfire. Any suggestions?????? Im about ready to pull my last bit of hair out
