Hi all, I hope someone may be able to help. A few weeks ago my VRSCR Street Rod would no longer idle when cold, although runs fine when hot. I suspected the IAC valve. I could feel it vibrating when the ignition was shut off as though it was trying to reset but jammed. I fitted a new valve but this is acting the same. The voltage from the ECM to the valve is reading around 10.4 volts while battery voltage is OK. Is this the correct voltage or is the ECM starting to break down?
