Car won't stop accelerating!!!
I was driving my car the other day and it was fine but than as i put it in neutral the rpms would stay at 2500-3500 rpm. Then when it was in gear it felt like it wouldn't stop accelerating. I checked the tps wiring by slightly wiggleing the wires and the idle would jump around. I replaced the harness and the car ran perfect for a couple days. Tonight i drove it and as i downshifted into 3rd and then let of the gas and wouldnt stop again i dropped it in neutral and went up to 6000 rpm so i shut the car off and checked everything it all seemed fine so after a while with it off it went back down to idleing at 2500-3000 rpm and drove home like that but as i drove home it went back to normal. I'm gonna do a boost leak test later today see if i find anything. Has anyone had this problem before???
