>>Well, My problem is not the vacuum its the idle speed motor.<< They do fail, although it's usually a mechanical failure rather than electrical. If so they can be repaired if you have the proper tools. In fact, if your's turns out to be bad I'd be happy to take it off your hands. There is a straighforward procedure for checking the idle speed system and wiring, it can be done at the connector to the ECU. This assumes you have everything else (throttle linkage, etc) set up correctly. To check *only* the idle speed motor/valve, start the car and keep it running. (set the idle manually if needed.) Disconnect the connector at the ECU and jumper terminals 1 and 4. Leave them jumpered and then jumper terminals 5 and 2. Rpm should increase. If engine rpm remains unchanged your idle speed motor/valve or the wiring to it is bad. 5 and 2 will drive it open, 3 and 2 will drive it closed. You could also do this with the motor off the car and watch it's response. Another way is to remove the tach input signal (push out terminal 12) to the ECU. This will set the idle motor to it's default position assuming its working. Then see if the car will at least run without you having to intervene. There are other ways to test the system depending on your skills and available equipment. If you want a complete procedure to test the entire system on the car (with minimal test gear) contact me off list.
