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.

How / where do I get codes?

Dealer, independent BMW shop, some auto stores like O'Reilly's have readers too. Call around, most of the auto parts stores will do it gratis :thumbup:
Thanks. Praying its not a big repair :(

Try running a bottle of techron concentrate plus if you want to try something inexpensive to rule out fuel clogging problems, I think the bottles are < $10.
