Thanks again for the tip J.M. Engine wiring harness replaced in 2003.

I wouldn't be able to build the code reader based on my current knowledge levels (and not much spare time available to train up).

The starting problem has grown more frequent now, happening daily with hot or warm engine. Only cold start is good.

Will be taking the car to the shop & post back on the remedy. Hopefully it's not the throttle actuator. Cruise control works fine all along.
