Engine Performance problem
1986 Ford Ranger 4 cyl Two Wheel Drive Manual?21000 miles
My truck is having this problem about 50% of the time.
When I am driving my truck starts sputtering and cutting out (as if it's not getting enough fuel or air). If I smash the gas peddle 3/4 the way down the truck takes off just fine. When I let off to cruise (no longer accelerating) it starts coughing and cutting out again. It does this at every gear (5 speed).
I have replaced: Fuel pump (both of them), Fuel Filter(both of them), TPS(set it to the right voltage), spark plugs & wires, air filter, distributer cap, distributer button, coil. I checked the O2 sensor(on the intake manifold and in the air intake/filter housing).
