Stalls at idle. Gas pedal keeps the engine running

Disconnecting MAF the car works so much better (starts with no problem and 800rpm idle but still fluctuates a bit). So, I plugged another MAF (from junkyard) but it gives me the same as before.

Reading codes (with the second MAF):

P0130 oxygen sensor ahead of catalytic converter (cylinders 1-3)
P0150 oxygen sensor ahead of catalytic converter (cylinders 4-6)
P1117 oxygen sensor heating 1 ahead of catalytic converter
P1121 oxygen sensor heating 2 ahead of catalytic converter
P1318 misfire, cylinder 6, emission related
P1316 misfire, cylinder 4, emission related
P1317 misfire, cylinder 5, emission related
P1313 misfire, cylinder 1, emission related
P0306 misfire, cylinder 6, damaging to catalytic converter
P0304 misfire, cylinder 4, damaging to catalytic converter
P0305 misfire, cylinder 5, damaging to catalytic converter

note: european car so it doesnt have the other o2 sensors (behind)

Maybe I was unlucky buying the MAF from junkyard?

The misfires are concentrated in bank 2. Could it be an o2 sensor?

The first thing you need to do is get a new MAF sensor.
I would only use a Bosch MAF sensor these cars don't do well with other brands.
Second: Your O2 sensors are not working. I see from the codes that both O2 sensors have the same issues. Could be a wiring issue. Could be that they are both shot.
Third: The misfires are not related to O2 sensors.
I would look at the coil packs on the plugs. Look for cracks or your sprark plug tubes could be leaking oil causing the plugs to short out.
