Running problems need help

So I'm loosing the battle with my 2001 330xi has 155xx miles.



The car runs rough at idle not to bad with throttle open at full throttle it Boggs down.



With the maf disconnected it runs better until the car warms up the starts running rough again. It will start missing while crushing and shifts hard assuming from the maf being disconnected.

It had 1 code for the maf ( I disconnected it)

And 1 code that was iacv stuck shut



I have tried:



Smoke test for vacuum leaks

Cleaning the maf

Changing coils around

Spark plugs

New intake boot

Intake gaskets

Disa valve





I'm lost the car does not want to cooperate for me.i need help solving this ASAP kinda need the car. What am I missing here?



Here are the recent codes that came up



p1085 p1345 p1343



Clogged fuel filter? With the maf plugged in it will idle until it dies



I can hold it at wot and get 4500rpm and that's it



Maf unplugged it revs fine but starts to miss at idle and while driving sometimes?
