Top end miss
Okay so i have a '94 Ford Ranger 4X4 with a 4.0 v6 and it runs okay just as long as you keep it under 50 and it doesnt go into overdrive. But once it hits overdrive goin about 50-70 MPH it cuts out real bad and even backfires on occasion if you stay into the pedal. I've replaces both of my O2 sensors on my exhaust, my MAF sensor, coil, plugs, wires, fuel filter, fresh oil change, new fuel cap, and at idle its pushing about 39 PSI of fuel pressure. Any suggestions or help would be greatly appreciated. Could it be my speed sensor or injectors maybe?
