I have a 2000 Ford Explorer 4X4 V6 SOHC. I have these 4 codes coming up, P0171, P0174, P0442, P1260. I am wondering if it could just be one thing that is wrong? I have changed the gas cap already and that didnt change anything. I can reset the codes but once the vehicle is at operating temps, they come back......any suggestions would be great!
