Thanks. I put on a new OEM BMW crankshaft sensor, swapped fuel pump, swapped MAF. Camshaft sensors replaced by mechanic while I was having surgery.

I did clean the IACV but didnt relubricate it. I recently saw the bouncing idle when slowing to a stop. The stall only happens when slowing down to a near stop. Always in transition to idle and only very rarely. Like 100+ times it's fine, then it stalls with basically no warning.

Mechanic said nothing else we can do, so I've returned back to the IACV.

You know pelican parts sells the URO brand IACV, so I don't think it's total crap.
