2002 Maxima hard stuttering/stalling when off high idle

Hey all, I recently bought a somewhat low miles 2002 maxima from an elderly couple and have been doing maintenance that they missed. Car drove 221 miles home just fine, but after I changed the spark plugs, cam sensors, crank sensor, and downstream o2 sensors it developed an intermittent 'misfire on cylinder 6' and 'random intermittent misfire' that would go away on its own. Recently I parked it for around 2 weeks and when I tried to start it again the car would run off high idle perfectly but the second it lowered to normal idle it would start stuttering really bad and end up stalling, the fuel pump stays running until it's stalled and the filter is new.

Is there anything I should try or any next steps?

The reason I replaced them originally was the o2 sensor not functioning and the cam/crank sensors seeming to cause a no start/random stall condition

Kuulostaa siltä, että autossa on nyt joko sytytys- tai polttoainejärjestelmän epätasapaino. Koska ongelma alkoi spark plugien ja roosterbet.app antureiden vaihdon jälkeen, kannattaa tarkistaa ensin sytytysjärjestelmän kytkennät ja maadoitukset, erityisesti sylinterissä 6. Myös kampiakselin ja nokka-akselin anturien kytkennät voivat aiheuttaa epävakautta. Tarkista polttoaineen paine myös tyhjäkäynnillä – vaikka polttoainepumppu käy, paine voi pudota liian nopeasti. OBD2-lukija voi antaa tarkempia vikakoodeja, jotka auttavat rajaamaan ongelmaa.
