i/m getting horrible gas mileage on my 1993 ford ranger ext cab 4by 4 .......ive changed the air filter spark plugs and wires but am still getting about 400 km to a full tank of gas ....ive just bought this truck about a week ago ........i just noticed that my low range lite is on is this normal???and could it be the reason im getting such low mileage .......thank s for any help on this issue ............

 

going to buy a new thermostat and pcv valve ............been reading here and i see that may help........any other suggestions would be appreciated thanks all ...........

 

Truck could be stuck in 4low . U can tell if it is by the way it drives like u can tell it geared low. Gunn it and if it feels like the front tires are pulling then ur truck is stuck in 4 wheel drive. Which most likely the vaccuum that locks tires is ****ed up or ur transfer case is ****ed up

 

turned out to be a bad lifter.......................
