KA Possible Bad MAF? Help me please.

I have a infamous 240sx idle issue. Im bogging something awful and a horrid shake under load till around 2k then after that it's nearly normal. The weird thing is if i spray some b12 carb cleaner directly on my pod filter it seems to idle normally. I have dumped around 4k into my engine bay just trying to not make it 4.5k. I guess a silver lining is that everything is new but, realistically could have just sr swapped it.


I have replaced the tps twice (first one was faulty), injectors, fuel pump, spark plugs and wires, cap and rotor, ignition coil, engine (yes a new engine), fuel filters like 1 month old, o2 sensors pretty new, clutch, flywheel, battery is 5 months old, alternators tested, water pump, oil pump, etc.

basically everything but iacv, maf, knock sensor, and i guess ecu.
