My 1993 3.0L auto 4x4 ranger cuts out and backfires when you put the gas pedel on the floor. If you don't let up truck will cut off. I have checked fuel pressure, changed fuel filter, spark plugs, wires, and air filter. I have cleaned the MAP sensor and took off the cats. Still having the same problem. Truck runs fine until full throttle. I'm thinking maybe the throttle position sensor.
