Phil, Two things to check. #1 Is the connection on the top of the idle speed motor good and tight. Is it getting power and opening the valve when the throttle is in the rest position. #2. Since it sounds like it's choking down. Turn the bottom idle screw clock to open up the throttle body butterflies a little more and then see what happens. Be sure to not flood the car by trying to keep on cranking it. If need be, unplug the cold start valve and try it again.

When you turn the key, It fires up and as soon as it settles down to idle it dies or if it does run, runs rough and dies if you step on the throttle. >>
