ive been searching up on this all week and havent found a solution. my car had been like bucking on acceleration unless i floored it in every gear. then it would just stop accelerating and drop rpm a for a few seconds before accelerating again. now it wont even hold idle i can rev it but when i stop it will just drop rpm, and when it hits about 1k from there gets rough and dies. theres smoke coming out but its been sitting a few days, doesnt burn oil or coolant.
heres a list of things ive replaced in the last few days.
MAF

IACV

AAC

Fuel Filter

Upper Intake Manifold

Throttle Body

Removed emissions and capped ALL vac areas

Distributor

Air Regulator

i can find no air leaks but its running like it has one. heres a video of it

POS 240 - YouTube

any ideas on what the hell it could be?
