bogging while accelerating- 94 f150 4.9L
my truck is bogging down in all gears(manual), it only bogs down when i try to put it under heavy acceleration. ive replaced the plugs, wires, cap,rotor,and fuel filter...still no improvement.what could this be? injectors? coil?sensor? i just need some answers as to what it may be and how i can fix it. im not to good with mechanics so please bear with me.
