lowering the idle

how would u lower the idle on a 94 nissan pick up, nothing seems to be wrong it just idles too high what can be done to lower it?
thanx

should be a Idle Air Control Valve which has a phillips screw on one side of it. that screw contols idle speed. also, you can adjust the TPS sensor to lower or higher idle. but if you adjust the TPS sensor to much, the car will feel sluggish.

good luck...
