Poor MPG...o2 sensors?
As the title states, I'm getting really bad MPGs....I filled up today, calculated the MPGs- came out to 11.4. That's horrible, granted it's a 4x4, but it shouldn't be THAT low. So my question is could my o2 sensors be a factor playing in? I'm pretty sure that they are old- not throwing any codes, but would it be worth it to go ahead and replace them? I have about 250 pounds of gravel in the bed for winter traction..but it should have that much of an effect. Anything else I should look at?
