Slow on Take-off
 
ok the GC is starting to be a dog on take-off
but just on take off when im goin 30ish and whomp it ... it goes
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

so k&N intake (just cleaned) newer FM super 40

what are the recommendations? tuneup?
which plugs do you recommend?
fuel injector cleaners?
sea foam, stp?

oh and BTW I just bought a welder so I can finally install the rear KMA

o2 sensor? and is it a v8? v8 ho? i6? does it idle rough? or smooth?

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.
