Your engine has a vacuum leak, causing the idle to peak. Check all the hoses under the hood for vacuum leaks. You have a leak some where for sure. Thanks.

this is the IAC failing not TPS, the tps only signals to the ECU
that you are at idle.

High idle on 86 Ford Bronco II (2.9L). Have replaced IAC, TPS and ECT. Also checked all vacuum lines. No fix. Need help.


I have heard of coolant sensors staying cold and keeping idle high but not a particular model.

Why does my car sometimes idle high with the clutch engaged but return to normal when vehicle comes to a stop?


The TPS can play funny tricks like this. Also sounds like a throtle linkage problem as well. Do u mean disengaged rather than engaged?
