The throttle positioning sensor is at fault. Two button head screws hold it in place at the throttle body. This part has a built in reostat that has very thin windings and a lever rides on it. As you increase the throttle this lever will move up. In time the windings get a carbon build up and eventually burn causing the throttle to become erratic such as in your case. Simp;y buy a new one and install it and it will be running like it should be

96 Harley Davidson 1200 sportster won't idle down staying stuck half throttle

Hi, Harris and the usual suspects are:
1. Throttle cables improperly adjusted.
2. Pull cable pinched-dirty-rusty needs lubing or replacing.
3. Return throttle wheel spring or cable broken.
4. Idle adjusting screw needs to be backed off.
5. Air fuel mixture adjusted too lean start with 2 full turns.
6. Intake system air leak.
7. Fast idle choke ramp is not releasing.
8. Broken throttle return spring.
9. Damaged diaphragm or slide.
10. Faulty MAP, TPS, ATS, O2, sensors or wiring/connector

What Makes a 1990 cutlass calasis idle fast.

Could be a dirty or stuck throttle plate, faulty idle air control valve, or a large vac leak.
The computer controls the idle speed by regulating the amount of air entering the throttle body thru the control valve.

When I first start my 99 electra glide classic, it idles at about 1k. If I then blip the throttle, the idle drops to about 400 rpm. It remains there until I ride for about 20 minutes. Then it stays at...

If your bike is fuel injected, this is typical. What is happening is the fast idle is keeping your engine running until you blip the trottle. When you do this, the fast idle relaeses the idle speed control. Once the engine gets to full operating temp, the idle speed is correct.

Good Luck

Starts up like normal but jumps up to about 3 grand on the tach then falls down to 1.5 and stays there, engine surges at this idle. Runs good on the road till u have to stop and surges(jumps a little)....

P1294 indicates a vacuum problem or a idle motor control problem. Since you already checked for vacuum leak then the iac on the side of the throttle body will need to be removed and cleaned. The best thing to do is remove the whole throttle body so it can be cleaned as well - both with carb cleaner. The idle solenoid (motor) on side of throttle body should be removed to do a through cleaning. All of the black needs to be removed from inside both before remounting to the intake. Make sure all connections and bolts are tight before starting engine.

High Idle and Torque Converter wont lock in all the time

i would check the iac valve on all three of your vehicles and on the ones that are sticking and wont idle down i would also verify that the throttle plate in your throttle body is not hanging up on a bur or something.
