Hey guys . When I'm driving and fully put my foot down on the pedal sometimes (not all the time) it just won't rev like it used too! It slowly goes from 4...5....6.....7. It used to shoot right to 6-7. What could cause this? Is it known as misfiring? Thanks! By the way I have a 2006 325i

Could be several things from clogged/dirty injectors, bad fuel, failing coil(s), dirty fuel filter, throttle potentometer, transmission issues, VANOS blah blah blah - your best bet is to see if there are some stored codes.

See, those generic scanners Autozone and other minimal, not too skilled vendors use simply don't see everything. Often don't see anything.

Yow! Averdi, you gotta read more here....
So, for a mere $287 and perhaps a license for Windows software ~ $80, he's better off than an indy visit, remember, this kid says he's 'broke as a joke'.
