Rb20 random rpm drop and die

Hi guys have been having a little gremlin lately with my gts4. Find at random when car is in neutral and coasting to a light my rpm will drop low and cause the car to die, I have also had it happen while sitting at light not moving idling fine at 1k then rpms start to drop, sometimes it chatches itself and revs jump to ~1200 other times it dies. Each time it does whether coasting or just idling it starts right back up like there was no issue. Drives fine 95% of the time though. I have idle set to 1k currently, have pulled IACV and cleaned that and adjusted the spring 1.5 turns tighter.

Pulled the aac off and found I forgot to replace the oring between the solenoid and the aac housing. Installed one and took the car for a drive Rpms still occasionally would drop but car never died. I also didn't reset the ecu which I should have done. Will keep this updated if this fixes it
