- 1991 Explorer Eddie Bauer
My 1991 Explorer will start to idle at a very high rpm (1500 to 2000), it usually idles normally, but will idle at a high RPM after a while of idling normally (sometimes a week or two of normal idle, sometimes just a day). While troubleshooting I noticed that when disconnecting the throttle position sensor, the idle goes to normal, and then reconnecting the sensor the idle is fine for some time again. I replaced both the throttle position sensor and the connector, but am still having this problem. Disconnecting the throttle position sensor and then reconnecting it with the engine running seems to correct the problem for a period of time (from a day to a week or two), but then back to the racing idle. Any input would be greatly appreciated.
