Throttle actuator A control system is stuck closed

This sounds like a very dirty throttle body. On the turbo cars it's pretty hard to get to the throttle body for removal and cleaning. I'm not sure about non-turbo.... Either way, a good throttle body cleaning should help out with this code.

2003 gmc envoy xl 4wd 5.3 litre idles low and stalls mainly when parking but sometimes also when coming to a stop...have replaced many parts already.

Hello: Get some carburetor cleaner, remove rubber tube going to the throttle body. Spray cleaner on rag and open throttle plate and clean all black stuff (carbon) off the throttle plate and the inner bore of the throttle plate. Make sure its clean, You can spray some in the throttle body but not very much as too much and you cab blow the engine up. If build up is bad (carbon) go to Auto Zone and purchase a small brass bristle brush to help remove carbon.

How do you set the throttle position sensor on 1999 jeep grand cherokee 4.0 litre

That sensor is not adjustable. It slides onto the throttle shaft and is screwed in place to the throttle body. Idle speed is controlled by the computer by adjusting air flow through the idle air control valve. If the idle is too high (you did not say) first clean the throttle body bore and plate, then if necessary remove the control valve, cleaning out the passage in the throttle body and carefully cleaning the valve itself, without turning the plunger. If that does not help, you will need to do electrical testing on that and other components to find out what's going on as well as checking all vacuum hoses attached to the engine for cracks or leaks.

Have you tried cleaning the throttle body. Use throttle body friendly cleaner as it has a special coating that you do not want to damage it. Clean the sutt out real good where the butterfly valve is, inside and outside.

sometimes the gasket under the trottle body goes bad. spray carb cleaner at the base of the trottle (not down into it) body while the engine is running. if the idle changes your on the right track. its an easy gasket to change.
