Does any one know where the Throttle position sensor is located? Any pics would be nice. Anyone know how to adjust those? My idle is at 1500 and I tried to adjust the throttle back and the air control. Nothing is bringing it back so I want to try the TPS.

It's on the throttle body towards the firewall.

Here's a TPS adjustment writeup. BTW, if you have a PFC and commander, you can read the TPS voltage values on the commander. A lot easier than using a mulitmeter.

You probably have a vacuum leak then.... adjusting the TPS won't do anything to fix your problem.

Check and see if you have a hose popped off under the throttlebody, or make sure you check your map sensor hose. If that pops off it will idle high as well and run like ****.

Do you have a Power FC? If so, you can easily check the voltages under the 'etc ' menu. Look under VTA1 and VTA2, the first one should be between 0.1 and 0.7 and the second between 0.75 and 1.25. This is when the car is warmed up, with the throttle closed.
