2000 Sport Throttle Position Sensor

[LindySport]

Oaky folks, what is the purpose of the throttle position sensor, what happens when it fails (in terms of symptoms) and what can I expect in dealing with replacing one?

My problems include no Idle, but the engine runs much too strong to suggest ignition, or fuel delivery. Air filter/fuel filter are new. It doesn't miss out at all over idle.

I'm stuck! Feel free to toss any past experiences on here.

no idle ?

As in unless you give it gas it stalls ?
If that is the case it is likely your I.A.C. valv ( Idle Air Control )
A VERY common problem on our explorers.
Good news is it is a very easy fix and not a very expensive part.
Search IAC and you will see it is quite a talked about problem.

oops! edit to commence in this thread. It will hardly idle, as in no throttle applied. ON a good day it will, but the idling is nothing different than you would hear on an antique tractor. i'm talking under 500 rpms, erraticaly. most of the time it results in stalling, however.

Go with the IAC. I did it on my truck and helped. Here's how to clean it.

It's a good place to start. Good luck

It does sound like an IAC issue, not a TPS issue.
