V6 Mustang, my problem is when cruising on the highway when I let off the gas my Rpm hangs at about 3000 be fore dropping down to about 1900 rpm at idle.No check engine light and the engine runs good otherwise.Was thinking maybe a bad TPS (throttle position sensors switch or maybe sticking EGR valve.Any help would be greatly appreciated. Thanks!!!
