1991 Ford F-150 Q&A

1991 Ford F-150 Question: throttle sticks at about 1100 rpms

The throttle sticks at about 1100rmps at idle. If I tap the top of the throttle body it drops down to 750 to 800 rpms. I have changed out the TPS and the Idle control valve. How can I be sure that I put the Throttle position sensor correctly? -

Here's some info from a ford forum and it sounds like debris might have gotten onto your IAC and it needs to be cleaned here's the forum http://www.ford-trucks.com/forums/709668-high-idle-after-cleaning-throttle-body.html Hope this helps -

Thanks for the recommendations. It is raining here so I will have to try cleaning the idle control valve when it stops raining. Does anyone know how to replace the throttle position sensor correctly? Jack -

Jack Ask your question again about the throttle position sensor because it needs to show up on the header -

on the left side wait till engine is cold there is a semi round sensor near the throttle body with 2 torx heads t20 remove them gently. replace tps and start the screw even more gently the tps only goes on one way.plug back in and set idle to 1000 rpm -
