Question about 1996 Ford F150 Regular Cab
The solution given to me was mass air flow sensor. I replaced it and am continuing to experience same problem.
O.k. This is generally caused by the mass air flow sensor, that's always first. There is a small belt driven air pump that has a couple of hoses that come off of it and route to the intake (or to the top of the engine) and the exhaust, there are in line check valves on the hoses. This system directs air either to the heads or the cats (catylatic converters). Check to see if the pump has gone out, a check valve is stuck, a hose has collapsed or is cracked/broken allowing air to escape, or if a vacuum hose, that runs to it, is cracked/broken or come loose, and sucking air. This is just an emissions requirement, and when this happens it generally doesn't make the car run any differently, it just throws a code. CHeck these and let me know
