Catalyic Converter and O2 problem...
The car is a 99 Civic Ex coupe, i was throwing a code for the catalyic converter. I replaced it with good used 96-98 civic ex oem cat. After driving a few miles i threw the same cataylic converter code again. I'm sure the cat i bought was good, is it my 02 sensor? Does it need to be replaced? Or am i still throwing a code becuz i'm using a 96-98 cat? I checked the part #'s on both 98 and 99 civic ex 02 sensors and they are both different. LMK thx guys
