How should I test the 3 wires that go into the map sensor? Where does each wire go from the map? Black wire=ground? green=? grey=? The motors starts to run real fat when a map starts to go out. Thanks Matt

What is the trouble you experience with the engine?
If the MAP sensor is shot the engine will run but very rich. It will basically smell unburnt gas all over the place. You can try by disconnecting the harness to the MAP sensor and observe the engine. If it runs as bad when you connect the MAP again you do have a problem in the MAP or in the wiring. Also you may get a trouble code if there is a problem with the MAP.
