SOURCE: low fuel pressure
U 1st need to test fuel pressure at the fuel pressure test port on the top of the engione in the fuel supply rail to the injector tops, it looks like a metal tire vale stem, u will need to buy a special fuel pressure tester to do this test. U should have around 55-60 PSI at idle, it should go up when u gun the engine but never go down, if it goes down the fuel filter or pump are suspect.

Pull the rubber inlet hose off at the throttle body and check for carbon build up around edge of throttle plate.USE a old toothbrush and some spray throttle body cleaner that can be purchased at autozone or othertype of parts house. Hold plate open spray and scrub with brush front,back and edges also make sure the idle air bleed hole on plate is open.

My experience has been with later model vehicles, but a bad throttle position sensor most definetly causes this type of situation. Two torx screws, opposite side if the throttle body, should have a three wire plug.
