I'm building a factory five roadster using a 1996 Mustang GT donor with 4.6 L SOHC motor. I started up the rolling chassis for the first time this past weekend. The engine idles a little high for the first minute or so, then it drops to such a low idle that it stalls. Is this a problem that is caused by the idle air control valve. My chiltons manual at 4-19 says that idle speed is not adjustable on this motor, that I need a special SCAN tool to extract working parameters (voltage signals) from the EEC-V system while it is running, which chilton says must be done by the dealer or shop with this equipment. What is the easiest way to check the function of the IAC.
Thanks
