Have replaced fuel sensor, pulse sensor, fuel filter, oxygen sensor, and it only happens when check engine light comes on. when I turn off the check engine light i get great gas mileage. The codes have been P134, P138 things that have to do with fuel. I do keep the car well maintained but every 1000 miles the check engine light comes on and there goes the gas mileage. Any Ideas????
