Someone please help. I have a 2002 w/an E30 M3 engine and have a hesitation problem that is driving me crazy. It does not hesitate all the time and sometimes I can go days w/o it happening. The hesitation is very quick as if I quickly took my foot off the gas and then got back on it. I checked for fuel pressure problems and ignition problems, both were fine. The engine is stock except for a Turner chip (I put the stock chip back in and it was not that) and a cone air filter from BMP. Has anyone else had a similar problem?? Thanks for the help.
