my sister in law drove her just tuned up cherry 85 prelude 2.0 si into a ditch. body wise it just bent the fender a bit and ive already replaced it. However every time you try to start the thing, the idle just climbs to max rpm and stays there. i had two ideas. one being the tps but that wasnt it when i hooked up a new one. the computer isnt throwin any codes, but i have a feeling thats what the problems going to be since there is no throttle response and im not even touching the gas pedal. any other ideas?????

thnx

 

did you check to see if the throttle cable was stuck open?

 

That can't be good on a cold engine. I'd definitely figure it out before you take many more attempts at starting it.

 

You changed out the TPS so I assume you looked at the cable and rotor on the throttle body and made sure it was closed. Check to make sure the rotor turns - open and close it.

 

i had the same problem... what would happen is the RPM would just climb and climb and climb.. for me it was a mixture of the IAC valve and the fast idle valve
i hope this helps

JOey

 

throttles fine, linkage is fine. i plugged another tps sensor still on another throttle body that would show it still closed and it did the same thing. ill check the iac and fast idle valves next. did you have to replace the valves or just needed adjustment?

 

where is the Iac on these? i cant find it in my manual? thnx again

 

n e one? i cant seem to find it anywhere. i have a 2.0 with fuel injection, 85
