Throwing Codes. What Is Wrong?

GQ335i · 01-25-2012, 07:34 PM

Hi Guys,

My car has been idling a little rough lately and taking longer cranks to start up. Dealer just replaced my Spark Plugs about 5,000 miles ago and replaced the HPFP about 10,000 miles ago, Unfortunately, my Injectors do not fall under the recall according to the dealer so they were not replaced. I think it may be my Coilpacks or Injectors and really hope it's not the HPFP again. I just read my codes via the JB4 Interface and the following codes were displayed:

2AAF Fuel Pump, plausibilty
29CD Misfirings, cylinder 1
29CF Misfirings, cylinder 3
29CC Misfirings, several cylinders

What do you guys think? Thanks!
