I seriously just got 12 mpg. I noticed it was kind of wierd after the CEL came on and the code was P1131. After some research here I replaced the rear bank upper O2 sensor (pain pain pain) and finally (105000 miles) did the spark plugs and wires and a fuel filter...Then the charging light came on and had the alternator replaced. What else can cause such poor gas mileage?
I filled it up a couple of nights ago, and reset the trip odometer. At 22 miles the gas gauge read 3/4 of a tank. At 82 I was at half a tank. Filled up today and put in 7 gallons with only 82 miles on the odometer. WHAT IS UP?
I hope the O2 sensor and the plugs and wires and filter will make a difference. 12 mpg sucks! LITERALLY!!!
