Here is my trouble. I have a 1994 B4000 4X4. On the way home the truck died. It idles but when you give it gas the revs drop off.It was diagnosed as a bad mass air flow sensor.I purchased a brand new mass air flow sensor and installed that, testing the wiring at the connection as well. Ground, power, and power from the computer . All check out. The new mass air flow sensor does nothing that the old one did. Exactly the same situation. It idles roughly and revs drop off as you give it gas. If you disconnect the mass air flow sensor the truck runs fine, idles properly and runs well. Is there some sort of reset with the computer to "introduce " the new mass air flow sensor? No other work has been done on the truck recently, no manifold work or anything like that. The truck runs fine without the mass air flow on but I would like it to run properly with it connected as it should. Any solutions from anyone who has had the same experience or hints and ideas are appreciated.
