So 02 sensor is one thing to consider. Must the sensor that is at smoke exhaust pipe be cleaned?
Nd people raise their eyebrows when i say dat i used 10w30 throughout the life of a civic 2006 model till 268,000km, and never open up the engineblock
brother o2 sensor is never cleaned or repaired and o2 dont het bad easily get it diagnosed from a professional who can see o2 behaviour on graph and thwn decide mostly cat con is dirty just inspext it and get it cleaned
Ok
