Thanks for the info. I search the post for ICP Sensor, and found more info. Also was able to find info on it's location. Today I dropped by the Ford dealer and picked one up for $157.00. Didn't fill comfortable getting one through eBay. I know I could have saved some money; but one of the post mentioned using the VIN number to insure getting the correct sensor.
Anyway, the sensor is in and the idle is normal again. Thanks again 2 Stroker!
And thanks to everyone that contributes to these forums!
