Engine Performance problem
1995 Ford F150 6 cyl Four Wheel Drive Manual 95000 miles
I am having a problem with my 95 F150, 4x4, manual tranny, straight 6 pickup. It is having a problem where it lightly " bucks" when driving at a steady speed. When idling or accellerating everything seems fine and runs smooth, but has the rough type of cutting out while at a steady speed and load (40 - 45 in 4th, but also in other gears too).
I changed the fuel filter, performed tune up (plugs, wires, rotor, and cap, air filter) with OEM parts. Thought maybe fuel pump, but it occurs regardless of which tank I use. The thorttle body was also cleaned and I have used injector cleaner in my engine a couple of times. A friend took a ride with me and said he didn't think it was fuel. Could it be something with the tranny? Computer? Could this be tied to the EGR?
Any assistance would be appreciated.
