bad gas mileage?

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......

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.

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...

what MPG are you getting miles per tank is useless.

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

97 Ford Ranger Gas MPG

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

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

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
