I have a 91 GT converible,When I'm driving in any gear at about 2500-3000 rpms and I let off the gas it stays at 2500 rpms and won't go down. Stop the car rev it up and it still won't go down. Pop hood, unplug the idle control valve and it idles great. Can anyone help!!

Could be the thottle linkage! When the car is reving up I can turn it off and then turn it back on and it dosen't do it anymore. Does turning off reset something?

try this before you do anything, clean out the throttle body assembly. it gets a lot of build up that can cause your idle to do wierd things. take off the cold air tubing, and reach into where the butterfly is, and cleand out all that crud

Looked at throttle linkage, check, cleaned throttle body and idle air control valve, check, guy at parts store said it could be the map sensor, any thoughts, thanks
