Hi ... I'm troubleshooting a racing idle condition on a 91 F150 5.8 liter V8. Can anyone help me identify the sensor(s) on the Throttle Body ? Sensor 1 is to the left (as you are looking at the engine from the front of the truck), and Sensor 2 is on the right. Also I need to know where is the Throttle Position Sensor ? And do I have to remove the Throttle Body to get to the TPS on this model ? thanks

 

sensor 2 looks like EGR and sensor 1 look like IAC

 

Im not real sure about #2, EGR is possible but I think that is the large silver thing behind it. #2 looks more like something from the PVC.

I agree on #1.
