My car initially starts OK; but the Service Engine Soon Light comes ON in about a minute When I park it then start it again within an hour, it runs really rough, surges and the exhaust smells (the Light comes ON again, too). When I am travelling along, the light goes out (city or highway driving); but when I slow down (either taking my foot off the gas or applying the brake, the trouble light comes back ON again accompanied by rough running.
When I tried to retrieve the trouble codes, I got some weird readings: 12 OR 21, 13 OR 31 and what appeared to be 5-4-3 (flashes of the light).
I suspect I may have a bad Oxygen sensor.
