I did change the coolant temp sensor--no fix. Next step will be to check/clean the throttle actuator right where the plate shaft enters the side of the actuator body. I'm not sure, but perhaps some varnish/build up here could cause sticking. If that doesn't fix it, I might have the injectors cleaned/tested.....

If anyone else has ideas, I'd like to hear them.
