I've also seen it called an idle speed control sensor. On the 3.8 it's located on top of the throttle body, almost looks like a small tranny! Not sure exactly what it does, but if your idle is lower than it should be or jumping up and down this is usually the culprit.

Generally...

Ford calls it Idle Air control Sensor...But every after market place will have
some differnt name for it, but it will be similar enough to let them know what your talking about....They will know what you want

It makes fine adjustments to the idle (fast idle when cold, A/C compressor on, slower idle when warm, etc.)

Hope that helps a little.

ok well i know the idel air control sensor or the idel speed control sensor whatever you prefer to call it is located ontop of the throttle body..so my guess is that the TPS sensor is the little thing on the backside of the throttle body???
