2000 Subaru Legacy 4 cyl All Wheel Drive Automatic 140000 miles
After driving my car for about 20 to 30 minutes when I come to a stop the car will smell horrible like burning rubber. It will also have some light smoke comming from under the hood. The check enging light is also on. Took it to one mechanic, they said it was the oxygen censor. Took it to another, they said the code read cadalic converter. What is your opinion?
