ERRATIC IDLE IN PARK HIGH IDLE IN DRIVE

1993 Honda Accord • 214,000 miles

My car is idling from 2500 rpm to 1500 rpm at park. When I put it in drive the rpm is at 1500 rpm and does get any lower. I have tried to troubleshoot it by disconnecting the vacuum hose going to the map sensor and the erratic idling stops. I've also notice that if I disconnect the idle sensor the erratic idle stops. I have tried changing out the vacuum control box, switch egr valve, fast idle sensor, cleaning the and tighten the intake air control valve and nothing seems to be working.

MAYBE YOU HAVE A VACUUM LEAK ?

IT MIGHT BE SOMETHING OBVIOUS YOU CAN SEE AND POSSIBLY HEAR HISSING........AND REPAIR.....LIKE A CRACKED HOSE, OR ONE PULLED LOOSE

INSURE IF YOU DO HIS METHODS, DO 'EM OUTSIDE AND WITH A FIRE EXTINGUISHER HANDY

THERE MAY BE OTHER POSSIBILITIES.......IS YOUR CHECK ENGINE LIGHT ON?
