1994 ford ranger bogging down when accelerating what can i do -
Same as title above. -
cleaning the throttle position sensor gave me some relief. -
Runnabillity issues with 91 ranger. Bucking and misfiring, clutch is strong. Much worse with lower grade fuel. Believe it to be a fuel issue, was told checking things like air flow sensor, egr valves, and cap and rotor is good place to start, throttle body de sludge was recommend recommended as injectors get gummed up quickly on this model -
Hard start when cold and no power.Let off of gas pedal and power picks back up.Fix unknown? -
sputtering under slight acceleration can barely take off in gear at complete stop, have to get it up to about 3000 rpm's to get off the line -
engine has no power 3000 rpm max changed 8plug wires 2coil packs accelerator reg on rail checked fuel pressure -
Truck is sluggish when under a loud.. Switching threw 1 Thur 3 its just sluggish once I switch into 4th or 5th gear it like its misfiring really bag or starving for gas.. If I don't push down on gas pedal it won't shake no lost of power when that starts -
Mass Airflow code. Mass Airflow replaced (2). Coil Pack replaced. FUel Pump replaced. Check enginne light still on and code still says mass airflow problem. Missing, stumbling at low power - no torque. -
Ford ranger hesitates or bogs on the highway (under load or hills) unless i push the peddle to the floor then it picks up power until i start letting up on the gas pedal and then loses power. -
same thing, plus pops and farts -
