clogged cat or ?
96 dodge intrepid. I got a code 72 last fall, cat conv efficiency. it would come and go so I was not sure about its validity. the other day, the car flooded, -10F. I had to change plugs and it finally started but now it is running very rich. I am getting code 52 which means rich condition. my rear bumper is getting sooty from the black exhaust. is my exhaust plugged so the engine is running very rich or are my O2 sensors fouled by the flooding episode? dodges are sensitive to being flooded i have heard.
