ok so i have a 90 mustang gt with UDP, CAI and thats about it for bolt ons that I know of (sure it has nothing to do with what happened but thought id throw that out there). I was on the way home from work and was passing a lady to get in the exit ramp lane when the engine just started revving like gas pedal was stuck and the tach buried all the way to the right past 7, smelled the engine like it was smoking and had to cut off the ignition and coast to a stop off of the road. thought the gas pedal stuck so inspected it and it was fine. went back and cranked engine and it started up and started to immediately over rev again, so cut it off. had a friend come out and he suggested pulling the throttle position sensor and we did. cranked it and it ran fine with it unhooked, plugged it back in and everything seems fine now. but I dont want this problem again so should i replace the TPS with a new one or could it be something else causing it and just got lucky somehow when we unplugged it, please help. dont want to blow my engine. also considering it revved long enough that i smelled the burning oil do you think there could have been possible damage to the engine? rings or bearings? or for that short period should everything be on the up and up. I am def gonna replace oil just for the sake of good measure (plus id rather spend the $40 to be safe).
