I can't get the car to idle with the idle speed motor connected. It will idle when I disconnect it but very high. I've tested the idle motor outside of the car on a power supply and it's working (starts opening at about 5V and fully opens at 12V). But when connected on the car i'm not getting any voltage to it. I'm using the new ITB calibration and the car drives fine but no idle. I'm suspecting something's wrong in the wiring. Anyone have a good reference for the wiring diagram on a 2000 Si?

Check your tps voltage. What is it while idling?

when i had my itb's on my old setup i didnt use the iac valve and i dont see how it would work cause it would only be hooked up to one cylinder!
i say just take it off and disable it!! it only sucks when its cold out cause you have to hold the gas down to warm it up depending on where you have it idling at
