when I start the car up after it is warmed up it idles at 1700 to 2000 rpm. that relates to about 35mph. could it be the o2 sensor or maybe the map sensor? the check engine light doesn't come on. if I pull the wiring conector off of the map sensor the idle goes down to about 800 rpm but the check engine light comes on. any ideas would be appreciated. thank you

check idle air and clean throttle body
check TPS volts
check for vacuum leak
