4.0OHV is bucking need advice
My truck is starting to act up.. dont know what it is, so i need your help guys..
It usually happens around 30mph. the truck starts to "buck"... it feels like im going over a bunch of pot holes, but im not.. If i let off the gas it stops, if i put the pedal to the floor, it will grab, but its really sluggish, but after a sec it clears up..
sometimes it will do it at around 60 to.. i dont know what to do.. i have plugs and wires on order, could that be it?

Normally plugs and/or plug wires will cause a misfire, or bucking while under load. I don't think that is how you described your problem. I would scan
for codes, but I would bet on a bad MAF sensor.
