Let's you and me hang out by your right front fender a minute, eh?

-Remove your negative battery cable and set it away from the battery terminal.
-remove the breather hose off your throttle body and pull it and the air cleaner end out gently, not banging around the darned MAF sensor
-unplug that piece of crap idle air control solenoid that's just under the throat of your throttle body and remove the solenoid's two 8mm screws...
-remove the solenoid and its rubber o-ring (or what's left of it) from the TB
-go get your hayne's manual or your (say it ain't so...) Shiny and new FACTORY SERVICE MANUAL
-grab a digital multitester and a 6 volt lantern battery and test your poor, pitiful idle air control solenoid per manual directions.
-then go to napa and order a new one for about 104 bucks.

Afternotes:
Adjusting the Throttle Position Sensor and/or ICS setting is rather useless if you don't first remove all cable tension from the transmission kickdown cable on the throttle body's belcrank (auto trans).

Don't hook the battery back up if you're not finished screwing with the sensors.
