I have a 2008 135i. I'm having a mid range misfire as I get onto the freeway. If I get into the excelerator hard, there's no misfire. But, if I press the peddle mid way sometimes I get a misfire. The car doesn't trow and error codes. Anyone had this happen to them? Possible coil starting to fail? Possible injector going bad? Computer issue? Any help or input would be great.
