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?

 

put the old sensors back in for starters

 

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
