Maybe someone can help me out.

I just bought a 01 5.4L Super Crew with 98,000 miles.

This thing is a gutless turd. It does have 285 50/20 shoes on it but it should turn them over a little shouldn't it?

Also when I'm at 60 and going to pass it takes a LOOOONG time to get to 70.

Please help!!

 

Any codes?
Tune up time?
What mods?

 

Plug change does wonders.

 

what gears?? remember it is summer time

 

Maybe the cats are plugged.

 

Change the plugs, my 4.6 had the original plugs in it from 97 lol

 

Truck is bone stock.

3.55 gears

Oh yeah one more thing.
The best mileage I have got on the highway is 13 and the city is around 10.

 

you still running the original plugs, oil, air filter, tranny fluid and rear end fluid??
