Hi sebastian_personal, Welcome to 2carpros and TY for the donation

Start by checking all the vacuum hoses for leakage/broken/disconnected-then lnspect the intake manifold and throttle body if its leaking by spraying WD40 on the flanges if the idle smooths out that's where the leak is-also contaminated fuel will contribute to the randon misfires P0300

1. Vacuum leaks
2. EGR and PCV valve.
3. Low fuel pressure.
4. Dirty fuel injectors.
5. Mass Air Flow Sensor.
6. Oxygen Sensor.
