2014 750li never ending issues

[Aceadrian]

Hello all, i purchased a 750 last year at 98k miles for a hell of a deal. For 2k miles it drove like a dream and after that ive continued to have issue after issue and cant seem to find the root of the problem. The car will jerk when accelerating in low rpm, and the code irs throwing is MAF sensor reading low. I have clean then replaced both maf senors. Added cold air intake for more airflow. Neither of these were fixes. Ive also replaced all spark plugs, coil packs, and O2 sensors. Im still getting a read on the maf sensors so it cant be them. After speaking to some bmw mechanics they said cut your loss and sell it or sink thousands into maybe finding the problem. This is really a last ditch effort for me before trading it in for a pretty substantial loss. Any advice or guidance is welcomed. I will also accept any crap for buying a high mileage n63tu lol.

Exact code would be great. I think you're at a point where a BMW independent shop that (and make sure of this) has an oscilloscope and someone that actually knows how to use it.

You could have simply a bad wire, to almost out of range timing. A pico is the only way you're going to find out definitively without throwing more and more money at it.
