Default 01 ej22 Impreza help needed

I know its the wrong place but lots of ppl only visit the members car gallery and I want to have best bet of getting some help

I don't usually consult these forums for things like this due to the fact most people just want to ask a million questions over and over and never really help. so try to read this completely first before jumping down my throat.

To start off its 2001 Impreza L manual trans 100% stock.
It started having problems shuttering bogging down occasionally it threw a cel with misfires on cylinder 2 and some times 4. Since then has been a wild goose chase to figure out what's wrong.

Shows no cel for anything other then the misfires from the begining which now it gives zero codes with same problems

Its has had multiple sets of plugs all NGK gapped correctly
Multiple sets of wires used OEM set known good and then changed to NGK blues
Known good OEM coil swapped in
Fuel filter changed
All that did nothing but stopped it from throwing the cels for some reason
Tore the motor apart found the valves leaking on drivers side head sent the heads to be cleaned valve guides replaced and valve job did nothing
Test of the fuel pump showed low pressure when isolated from system so replaced that today still same problems

As of now it runs fine when it wants to short bursts. throws no cel or codes but it seems like the computer is causing the issue. It feels like it is pulling timing or fuel in steps until it almost dies. I can't really see anything abnormal on the scan tool but your limited what you can read any help would be greatly appreciated
