Where is the idle control valve in an '84 bmw and how do I clean it?

I have an '84 bmw 633 and it idles a bit high. Its also idling just a bit rough. I have checked bmw forums and everyone says it could be the ICV. Can someone tell me exactly where it is, and how to clean it? Thanks.Where is the idle control valve in an '84 bmw and how do I clean it?Using carb cleaner on an ICV is likely to ruin it. The spray takes the coating off the wires inside the unit and short it out. Try cleaning the throttle body with throttle body cleaner and use compressed air after spraying the inside area on both sides of the throttle plate. Make sure you have a bit of slack in the throttle cable so that the throttle plate closes all the way. Many vehicles relearn the idle rpm when you disconnect the battery for a minute or more. If you try that you will need to drive the car in stop and go conditions with the head lights and AC turned off so that there is no electrical load causing the ECU to send a signal to the IAC motor to increase the idle speed.

If that does not help take the car to the dealer and have them read the engine data to make sure the IAC motor is working.
