i get like 15 mpgs to 10 stock 22re the fuel filters never been changed my trucks at 274,478 miles i know that could be one of my main problems i kno i probably need a new air filter my plugs are good so is oil is there anything im missing you guys?

 

did you top off your alternator?

jk

 

was getting 24-25mpg on 205/75/14's in the rear.

now getting like 21mpg on 215/65/16's in the rear. either its that or i've been jacking around a bit (lol WOT and ****, i'll admit, i have been)

 

yea and i put some turn signal fluid to

 

thats funny cuz my truck (stock floored, bagged, heavy as sin) on 205/40/16 gets like 24 or so and it's a dang 4 speed.

 

is your speedo correct with your rim and tire change?

 

IS the thermostat stuck?
Computer stuck in open loop?
Open temp sending unit?
Leaking cold start injector?
Fuel Pressure regulator torn? Pressure?
Timing?
Brake/wheel bearing drag?

Lots of ideas there...

 

took the thermostat out and ecu is fine timing might be a little off

 

yea i had never adjusted it for the 17s but its correct for the 15s

 

An engine that isnt warmed up will run in open loop.

Pre-programmed rich condition. Was your t-stat out when this started? Im confused.

 

so if your spedo is off you are going to be getting a false reading for mileage. remember for every mile you are off thats mileage off your gallons.

 

the slightly taller 215/65/16's actually corrected my speedometer to GPS accuracy.

the 205/75/14's from factory are off.

 

I hate GPS systems they always send me in a circle and in the wrong direction. So i wouldnt trust those things. MY 2 CENTS

 

i do believe its it only reason it came off is because it did the iacv thing hondas do alot where it idled up and down

 

I'm running a Garmin 205W, they use it on Cessna private jets

and it reads accurate on every other vehicle i've placed it in.

 

i put a new thermostat in and it wasnt a cheap one either i didnt know that it affected my pickup my truck pulls harder i guess cause it reaches operating temp now hopefully itll bring my gas milage up

 

i know my speedo is off but i drive around with my gps and by that i am getting 23-25mpg with a 4speed 195/65r15 3:43 rearend... if i keep my foot out of it... lol

 

25ish on my 5 speed and a lead foot.

 

not if you know what you've traveled GPs tells me the miles, and I do the math.
