    Toyota Camry 1999: Bad smell after catalytic converter replaced

    Toyota Toyota Advice Toyota Camry Toyota Camry Advice Toyota Camry 1999

    My 1999 Toyota Camry V6 recently had the catalytic converter replaced. The car has more than 200,000km on the clock and purrs along but, pulling into the carport, I note the exhaust smells as though the fuel mix is too rich. A 300km country drive returned 8.0L/100km. Any thoughts? Oxygen sensors, wrong converter, perhaps the engine management chip is puzzled like me?

    It's what's called "seasoning" of the catalytic converter, basically as it burns in during early use. In a lot of cars, especially in the early days of converters, there was a rotten-egg smell from the exhaust gases. So, in my experience, nothing to worry about.
