If your cold start valve was open all the time, it would flood the engine untill it dies. It almost sounds as though your idle speed regulator is on the blink. When my idle speed circuit was down, I rigged everything up where I could set the idle manualy. When cold, the engine would idle about 800-900 RPM's. With the valve in the same position with the engine hot, the idle would jump to 1600 RPM's. If your idle is up around 3000 RPM's, then your idle speed motor is full open. After purchasing a new idle speed motor and ECU, the trouble turned out to be a faulty wire (black/green in my case). Here is the best way I've found to check the idle speed circuit. Using a voltmeter with the key in the "ON" position, check for 12 volts from the hot wire, and verify that the ground connection for both the ECU, and the microswitch is good (12 volts from the hot wire directly to the grounds). Another way to test the microswitch is to put the key into the "ON" position, and trip the microswitch. When doing this, you should hear the vaccum solenoid under the intake manifold clicking. For the wiring to the idle speed motor, try this. Insert a jumper wire between the hot wire and the wire you wish to test. In the engine compartment, connect the volt meter to the wire, and ground the connection to the engine block. Check for 12 volts on all 3 wires. Other then that, the only other thing I can think of might be a poor connection/signal from the white/slate wire. But before this, try checking all other wires first. I don't know exactly what you mean when you said your car "makes a lot of noise" when starting. Is the car having difficulty starting? Or is the just very high for those few seconds? Try that and see how things turn out. -Robert vin 6585 --- In dmcnews@xxxx, debruin@xxxx wrote: > I'm looking for some advise on a small problem I have.
