Idle problem integra


check the MAP sensor (manifold absolute pressure). The ECM (car computer) uses that to keep idle at minimum 750 RPM. It's normal for it to run high when cold. These small 4 banger motors typically run hot, and they won't run right IF they're NOT running hot, ergo the idle is usually high when it is cold so as to cause it to warm up quicker. If the RPM's drop below 750, suspect the MAP sensor, &/or ECM.

Probably the "idle speed controller",(the ecu is programmed with target idling speeds values to respond to different engine conditions, coolant temp, a/c on/off etc,sensors transmit signals to the ecu which controls the flow of air through the bypass of the throttle valve and adjust idle speed top target value)
however this what the manual says,
check for defective throttle linkage or cable
check idle up-up vacum switching valve
check coolant temp sensor
check throttle position sensor.
Usually if its major, then the check engine light comes on,

Engine rmps will not back down


If this happened all of a sudden, It sounds like a Vacuum leak. I would inspect the vacuum hoses for brakes or cracks. Is the Rpm too high to test drive and see how the vehicle is running?

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.
