Quick recap. Car is stalling off throttle while decelerating. No warning. No codes. Starts right back up. Brought it to a shop and they didn't do jack shit. No codes, drove it. Scratched their head and gave back to me. Here is a video of the main symptom. On occasion like once every 100 miles it just shuts off, think like bumper to bumper traffic. Not good. I've done and replaced a lot of stuff. So I need to be more pinpoint. Still seems to me like an idle Air control valve issue. When I'm off throttle and decelerating the rpm bounce when it gets to 900-1000rpm.
I'd be okay to buy a Bosch one for $120 but I also don't know where and where to trust. I feel like eBay is shady. Also eBay has the OEM bmw part for like $150 but also shady AF.

Weathers warm I'm ready to dig it. Car has good vacuum at the oil fill cap. Plugs are new, fuel pump is good, fuel filter is new, car runs great at higher speed and idles no issue. Doesn't miss a beat. It's really in the transition from throttle to idle where it's dying. There no jerking when it stalls. Ruling out torque converter. It just turns off and starts up again after I stop and put in park. Both cam sensors and crank are new. Maf is good. I've swapped around coil packs.
