Hey guys. Here is my idle speed control. It seems like it's stuck in the out position.

Going to be while the engine is shut down. Stops airflow to kill the engine.

It's a motor driving a worm screw.

Don't force it!

Should retract with the key on but no start so it gets ready to control air flow past the butterfly and control idle.

Clean the tip off and the little passage inside the throttle body with carb cleaner.

Tip should look like a little point which sets inside of a cone shaped seat.

That is the vent, no way to determine its functionality by sight. Cleaning would be a first step, be careful, don't get fluid in the motor end. A little goes a long way. A bit of lube on the metal shaft is a good idea too.

Hey guys, so I cleaned the iac and it really wasn't all that dirty. But then I got to thinking, my temp gauge has been all over the place and sometimes doesn't move at all. If my temp sensor is bad, not only would it explain the jumpy gauge but also everything else. If the computer thinks it's a temp it's not that could really do some major tomfoolery with the entire system.

No, the gauge runs off a separate sensor. Again, use the scan tool to verify ECT from the PCM. If that don't follow the gauge, replace the single wire sensor along with thermostat. Beyond that, these engines have issues with cracked heads, causing gauges to move around along with misfires.
