Ford f150 1996 142000: This truck has the 300 six and was running badly I had the codes read and it said O2 sensors were bad and mass air flow pending well after I changed the O2 sensors the light still came on and I had the codes read again the parts store said all O2 sensors heater malfunction but the mass air code was gone. Well I checked the codes myself with a actron OBD2 and the follwing codes were displayed p0112, p1505, p0135, p0141, p0155, p1443, p0414, p0153, p0301, these codes should make the truck run terrible I would think but the truck doesnt run bad but does still get bad gas mileage. Fuel pumps have been replaced also.
have the same problem?
