Help me with CEL!
My buddy has an 98 ls that is getting a code 67 (Catalyst System Efficiency Below Threshold- Malfunctioning catalyst system). What could actually be wrong. Is there some kind of a sensor on the cat, or is it an O2 sensor problem? Any help is appreciated.

that means it needs a new converter or you can try a fuel injection cleaning or a motor cleaning
