Low idle, shaking, shuttering...please help.

E90076 · 08-08-2008, 09:58 PM

I was just crusing through my parking garage a few minutes ago when my car suddenly started to drop in revs, shake, and make some terrible exhaust noises. I parked immidiately and restarted with no issues. Still havent driven it again yet.

Anyone have any ideas what this could be, HPFP perhaps?

Sounds like the fuel pump from everything I've read and experienced. My local dealer gave me a 335 sedan to test overnight and it practically quit on me. I had to limp back to the lot with it shuddering and making a lot of noise. They told me it was probably water in the gas from sitting outside so long - please! They never would tell me what the fix was but needless to say I didn't buy that one.

Update: just started up and picked up a limp mode.

It sounds like a fuel pump man. Take off your mods and take it into the dealership asap....

Thanks will do. Not mods except Dinan. OK on the car to drive it up there?

Read the codes with a c-reader. Could also be a problematic sensor located near the cats.
