Replaced the ECM. Fuel trims are wonky... Maf? Where can I get one that doesn't cost what I could sell the car for(I'm running condition lol) that Will actually work?

I'm going to replace the plugs, and probably both coils

 

Cylinder 1 is one of the ones that has the misfires. The cylinder is at 15 degrees BTDC. One revolution off, and I get 100 leakage through the intake at 0°. This leak I can barely hear at the tailpipe on that side, with my ear literally touching the tip (maybe the whole ocean in the seashell phenomenon) but mostly the oil fill cap. At 0 degrees, leakage goes slightly up

Have you checked fuel pressure to see if it is not too high or too low?
