2001 X5 4.4i issue NEED HELP

[JakeJB]

Hello everyone. This is my first post, and let me say ahead of time that I have searched both Xoutpost, and google, and have not come up with a definitive answer.

I sold my X5 to my mother. About a month later, this being last week, the car just dies in traffic. It restarted, and seemed to idle ok, but when pressing the gas pedal, it would studder and backfire, not moving forward at all. I had it towed to my house. I hooked my scanner up, and got the code P0102.

I tried the unplug the MAF while running trick, knowing that it may not be a real indicator, and it died. It runs the same with or without the MAF plugged in. I have checked the plug and the wiring, and it all appears to be good. I checked all of the hoses and lines, and can't find a vacuum leak. I then bought a new Bosch MAF, and hooked it up. Nothing has changed. I unhooked the neg. terminal on the battery, hoping to reset the computer. The only difference is the SES light is gone. It still runs as stated above.

Does anyone have any idea what could be causing this? I assume it is MAF related, but I am at a loss as to how.

Thanks!
