throttle position sensor, or check to make sure you have vacume going to the map sensor. Alot of times the outlet on the throttle body gets plugged and there is no vacume at the map--causes it to die. unplug the throttle position sensor and then rev it up and see if its better.

Can't engage 4X4 wheel drive or disengaging


Check the actuator (located under the battery plate). Remove the battery, then the plate, and you'll see something that looks like a horn attached to hoses. One side is soft, and may have a hole in it. This will cause the vacuum not to work, hence, your 4WD won't. Good luck!

You may have an air bubble in your coolant system. If so, use a large coolant funnel designed to purge out air bubbles. The funnel attaches to your radiator with cap removed. Check it out on line. It costs about $25.
