its got the 4.7L V-8 and runs smooth as can be idle is good smooth shifting and even engine tone throughout the power range

I m thinking cap rotor wires and plugs. If they are old. Some injector cleaner wouldnt hurt. I have the I 6 so Im not much help on what plugs or the way the 4.7 runs. Seems to me weak power under a load is a weak spark. Its a place to start.
