Default Misfire Help

So almost 1.5 years ago my m3 i neglected had crapped out on me a bit so I got another car til I felt like working on it. It was idling rough and stalling out. I had ran it by autozone and it gave me these codes:
p0300 random misfire
p0301 cylinder 1 misfire detected
p0304 cylinder 4 misfire detected
p0420 catalyst system efficency below threshold
p0430 catalyst system efficency below threshold
p0153 o2 circuit slow response (Bank 2, sensor 1)
p0113 o2 circuit slow response (Bank 1, sensor 1)
p0446 Evaporative Emissions System Vent control Circuit
p0340 Camshaft Position Sensor Circuit Malfunction

So fast forward now I replaced the MAF and Intake boot due to cracks. Now it's not stalling out anymore but still have a misfire and running a bit rich. Just wanna get an input on audozones codes accuracy before I dive a bit deeper and start addressing everything. Engine is at 239k miles.

The answer is more obvious than you think.

You need to replace the camshaft sensor. GENUINE BMW ONLY, NOTHING ELSE. A lot of those codes are related to the camshaft sensor.

Replace it, and then readdress the codes that may pop up. You might still have other issues, but that sensor causes a mess when they fail.

Do NOT buy the VDO "OE" branded sensor. There is a known issue with them.

Always good to start with plugs and coils with misfires.
