ok guys so I haven't been on the forums in a while forgive me in advance lol. but anyway my escort has a little over 170k miles on it now. I haven't driven the car in a few weeks due to the fact I was waiting for a new thermostat housing gasket and new bolts to fix a little leak but that's all taken care of now. so as I went to drive the car I could feel something wasn't right with the escorts idling. the car was racing almost as if power breaking. highest idle was at almost 3k rpm which was when in park or neutral. when in drive the idle still raced but wasn't as high but I had to keep my foot firmly on the brake so the car wouldn't take off. the car went to hot also due to the high rpm not moving. then as soon as I shut it car wouldn't start. I let the car sit a few hours went to start it and everything was fine until I hit the gas pedal then the crazy high rpm started again so I shut her down. has this ever happened to any of you guys?? id suspect a sticking throttle plate or bad idle air control valve. please if any help let me know.
