I get 12-13 but I am lifted have big wheels/tires and 5.4 What is everyone else gettin with the 5.4s?

 

im gettin 16 with my 5.4 with 285's. i think my gas mileage is starting to drop because theyre bringing in the winterblend of fuel. i was getting 19 mpg this summer

 

My anound town has dropped to about 15-16 now that the temps hav efallen, still doing 18+ on the highway, was near 21 last summer

 

That would be nice.... I can not beleive I am only getting 12-13

 

My truck usually get a little better during the winter, its like a free CAI lol. Well, not really, but you know what i mean.

 

What rear end do you have? I was getting 16-19 in my 02, It had the 4.6l 4X with a 3.55ls rear with the 265/70/17 tires.

The plugs are a lot easier to change than they look. I had to do mine at 47K because of a misfire on cylinder #3. You do not need to disconnect the fuel rail as some say. Do not use any anti-seize when doing them but make sure to use a torque wrench because of the issues with your engine not having enough threads and they are known for ejecting plugs.

 

same rear and tires as yours. Just picked up some plugs and I have to go back and get a torque wrench. How many lbs should they be set at???

 

My rear end is geared real low i had to replace it but cant remember what ratio it is. I cleaned my maf it seems to idle a lil better. I run 255/70/16r on my truck.

 

I don't have a manual to confirm but as I remember it was either 11 or 14 ft.lbs.

And when you go to do it it is a lot easier if you unplug the electrical connector to each injectors and you do them. It's pretty straight forward and you shouldn't have any problem.

 

Thanks for the info, when I went and got the torque wrench they looked it up for me and it's between 7 and 15 ft.lbs. The lowest the wrench will go is 10 so that will be about the middle. i will let you know how it goes. I truck is in my garage and i'm going to do it tomorrow.
