What a difference cleaning the MAF sensor makes!

Thanks guys!!

I was going to suggest cleaning out the throttle body by hand (you clean the "ring" of deposit left from where the plate closes) and getting some good fuel injection cleaner in your tank.

At your mileage, I think it would be a waste to spend 250 (which is ridiculous btw) on your truck.

That's not always true... If you put a set of 37's on an H2, you're effectively changing the gear ratio from 4.11's (stock) to say 3.23's (for sake of discussion)

Technically you'd be lowering the rpm and based on your higher rpm=less fuel logic, a driver should expect better gas mileage.

All of this is within reason. Anyone doing so will see a decrease of mileage of 2-3 mpg simply because the engine had to lug harder to pull the truck around. Turning over heavier, larger diameter tires will hurt gas mileage out of the hole and on the highway.

Where you may see an increase it cruising at about 45 in the city. (providing you're not stopping and going)

Just sayin'
