Took off idle actuator hooked up to power and it simply vibrates - nothing moves? Seems like it's stuck? Car won't start. Is something supposed to move inside?
Possible not sure, but as I said my car started and idled with wire disconnected and IAC just setting in intake with hose hooked up.So with a malfunctioning IAC the system may not start?
Ditto. I have mine set to open to pretty much the same figures on my motor. Idle when warm is 49% on mine, but who's arguing over 1% I also have mine set to increase the opening by 1% when the A/C clutch is pulled in. ECU controls this as well. When warm, my ECU uses timing to stabilise idle...... but I run my own ECU.
I have it set to open 75% at -40°C and 65% warm for starting
it runs around 50% for normal idle on my car.
Try reverse the polarity! There is a coil inside. When there's current passing through the coil, a magnetic force will force the inside drum to rotate in one direction. You will not see any movement if the rotation is towards a direction that is already restrained (by the spring and some stop perhaps). The humming noise could be from some very small back and fore vibration.I hooked mine up (Bosch connector only) and it did nothing - except make a humming sound. I will wait and see if car starts when I receive another IAC from Alfisti Steve.
Please, please you need to verify you don't have wires hooked up backwards in connector before you hook up my IAC because as I remember you telling me you did some kind of wire repair earlier.I hooked mine up (Bosch connector only) and it did nothing - except make a humming sound. I will wait and see if car starts when I receive another IAC from Alfisti Steve.
