1997 f150 4.6L 4x4
Brand New Napa wires, Autozone coil packs, Motorcraft Platinum Plugs
Cleaned MAF and IAC, Has new fuel filter and air filter, And premium gas,

While idling stumbles randomly but always stays running never dies, kinda like a slight misfire, in the #4 cylinder it has a insert not like a heli-coil but more of a solid insert.

Not sure whats causing the rough idle and also is it possible to tighten the throttle cable on the throttle body so i wont have to press the gas pedal so much to take off because when you look at it on the throttle body it has ALOT of slack !

Thanks Brandon
