the gas mileage keeps getting worse on my ranger. its got 65000 miles on it and i run synthetic oil in it and all services have been done, except the wires and plugs have not been changed. could that be the reason for the gas mileage?

if u are wondering i just got over 200 miles on the last tank......

 

the tires won't help. but change the plugs and wires. what kinda air filter you runnin

 

its an air hog drop in..

 

ive got about 200 miles on half a tank right now. usually get around 350 miles on a tank with a couple gallons left.

 

I know....I was like wtf? My lil brothers 4banger gets awesome mileage. My 4x4 4.0L with 4.10s and 32s gets more than 300 a tank.

Here's what I'd do, Pull your MAF, spray it with some CRC Mass airflow cleaner. You need something thats okay for plastics, and the CRC mass airflow cleaner is made for plastic. Change them plugs. Run a couple tanks with Lucas Oil Fuel Treatment. Weird at only 65000 that that little 2.3 is sucking the fuel. Pull off your IAC (Idle Air Control) and spray it with the CRC stuff.

 

no to hijak... Shane, what mpq do you get/what mods did you do?

Thanks.

 

i am having the same problem..I have a 1996 Ranger. Standard cab. 2.3L automatic tranny. Got about a 20gal tank and only get little over 200 miles off that tank. I have a new K&N air filter, new plugs/wires, clean the MAF sensor with CRC. I'm averaging about 16-17 MPG. I have 225/70R/14 tires at about 35PSI each..dunno anything else to do...maybe rip out that auto tranny and put in the 5spd i'v always wanted..lol...or better yet..put full coverage on it and drive it off a freakin cliff.lol. anyone else have any suggestions?

EDIT: i'v also added some prestone fuel treatment to it. And i onlt have 128K miles.

 

i think you need to look at 02 sensors. the engine has got to be running way rich for that mpg number, unless you're idling hours or towing a million lbs...or leaking gas all over...

 

standard cab should be 14.5gal tank?

what MPG are you getting miles per tank is useless.

 

i get about 10mpg

 

think it is a 16.5 gallon tank..... unless it has an optional 20gal one

even still it's horrible mileage.

even in the coldest part of the winter mine was still getting 20mpg pretty steady
with 50/50 hwy/cty driving. now it's warmer out my goal is to get close to 25mpg...

with the 20.5 gallon tank i should be getting near to 500 miles out of a tankful

 

just filled it yesterday and calculated the mileage...drum roll....

244.2 miles on 10.425 gal = 23.42 mpg...

looking to get better with new plugs planned for later this summer.

 

I have been having the same problem. I have a 97 Ranger with 151,000 miles on it. About 2 months ago, I started to see a drastic drop in my MPG. At first, I thought it was the gas I was using that contained Ethanol. I change my gas and still saw no drastic improvement. I am getting about 200 miles per tank right now. I have changed out both of my O2 sensors, my fuel filter, my PCV valve, had a full tune up last year (plugs, wires, etc.). I have run 2 cycles of injector cleaner through my tank as of now. It seems to have a decrease of power right when I take off then you can feel it "kick in". I have checked all of my vacuum hoses and they all seem to be intact. I have taken it to "The Zone" and all codes are clear. I guess I will try changing out my EGR next. Any other suggestions. How difficult is it to clean out the mass air flow and idle air control? Any help would be appreciated. Could my AC have any affect on things. It works fine but if there was a problem with it, could it matter. I know that when running AC, obviously there will be a MPG drop but not this significant. It has not been like this before. I have had the truck for 8 years and this is all new. Thanks

 

On my 2001 Ranger with a 2.3L I had engine codes ran and they were.......P1520,P1432,P1451,P0135,P0141. What do they mean? Thanks.

 

yes change your plugs and wires

 

will try that cheese man thanks

 

if you have a EGR valve
remove it and clean inside the manifold behind it

check the tube leading to the EGR valve for blockage
fuel economy rely`s on the un-restricted un-burnt gas flow to the EGR valve

 

Changing plugs and wires makes a huge difference. the person that owned my truck before me (my uncle) drove it for 150000 miles without changing the plugs. once i got it i was getting about 15-17 mpg. now after changing the plugs and wires i get about 22-24 mpg

 

new plugs and plug wires didn't help...checking EGR next......thanks

 

check to see if your EGR valve moves freely

if it is stuck

soak it in small bucket of gasoline for about 24 hours

it will loosen and dis-lodge the carbon

 

Maybe your problem is the thing attached to you...haha

 

i went from F to 3/4 in 30 miles last night 7.27mpg

Edit: went back to the same station same pump and filled back up 32.1 miles ate 2.909 gallons of gas 11.03 mpg
all city

 

what spark plugs are presently using

if they are iridium scrap them they are garbage

i switched to CHAMPION COPPER PLUS and my gas mileage went way up

engine idles a lot better better throttle response even cold weather starts are improved

 

stock motorcrafts im going to order some new stockers here soon the only thing ill use champion in is my lawnmower/weedeater

 

old thread but i swaped my plugs for autolite iridium xp's gas mpgs still low but my throttle response is alittle better

btw-belive it or not my stockers were ngk's all they said on them were Japan and a part number after searching the part number it comes up ngk's and no no one hade changed them before i bought the truck new with 10 miles on it
