Fixed it

turns out my cat was completely gutted out so I got a new one and it is doing a lot better

Good to know that it won't be a good idea to run gutted cats.

Cool, thanks for coming back and letting us know what you found.

 

[deerhunter3]

well I fixed the problems but I am still getting around 10mpg still is there anything else you guys can think of
like I sad I replaced about all the sensors and I was thinking about running a fuel additive cleaner to wipe out the whole engine.
any preferences?????

Seafoam.

Also, did you do a compression test?

 

[wynnespeed]

yes seafoam is what i prefer too

Get a voltmeter and check that you are getting current to all of the sensors. There's gotta be a reason your mpg is so sucky right now. If all the sensors are giving feedback to the brain, then I'd check for a gas leak somewhere or gas out of the tailpipe literally. Is the inside of your tailpipe black and sooty...check with your finger when the truck/engine is cold.

Have you checked your fuel mileage with a corrected distance? Bigger tires over stock decreases tbe odometer reading. Larger tire circumference means less revolutions per mile, means less miles showing on odometer. Also what gear ratio do your axles have?

well from autozone they have something to increase your mpg and also clean your enigine called CRC guaranteed to pass I am thinking to get that stuff and run that through also my FPR could be faulty from factory it is still under warrenty so I might replace that. Also, my bigger tires do throw my speed/ mileage off but even with that I am getting 12 mpg at best.

I did a compression test but I think the numbers were fine also I couldn't find any vacuum leaks
