i have A single 2001 ox66 225 that started to burn extra fuel, so i did all the regular usual maintiance, cleaned o2 sensor, lp fuel pumps not leaking, cleaned vst filter, changed the plugs. before i cleaned the plugs, all them had a oil residue which i think is normal. after new plugs the right side looks normal with tan color and oil residue, but the left side is much lighter with a very clean dry look... what would cause this..''
thanks for any help
