MAF help!!!!
Can anyone help me out, I got a EML and read the code it said Mass air flow sensor. So I got a new one from EBAY and put it in. I hooked it up with it's connector and then started my car. It started up fine and idled fine, but when I went for a test drive it would bog down and I couldn't get out of 1st gear. It pretty much wouldn't go above 2000 rpm and it sounded like it was chocking. So next I left the new MAF installed but disconnected it and started it again. it ran just fine and I had no problems. I've actually been driving it like this for a week now and the only thing not normal is I can smell some extra gas burn off when I drive, like it's running a little rich and my MPG is worse then it was before, but it drives just fine and the only EML i'm getting is the mass air flow sensor one. The old MAF was definitely bad because I could see both the little diodes things were completely gone. Is it necessary to get the ECU recoded after replacing the MAF? I'm not sure. If anyone has experienced this sort of problem any help would be awesome before I have to take it to the dealership and get jammed for a bunch of money with something I can probably do myself. Thanks for the help.

Pretty self explanatory. You need to get a new MAF, other than the one from Ebay. What brand is the one from ebay? It may not even be the right one for your car. I recommed Bimmerspecialist.com . Good prices and fast shipping. Overnight available.
