what are symptoms of catalytic converter failure
When I apply the brakes, the car interior smells like a burnt candle! It doesn't do it every time, but it is happening more often. I wondered if this could be the catalytic converter going out or something with the exhaust system.
If it happens when you apply brakes than it's not related to the CC in any way. Symptoms: Oxygen sensor code coming up more often- Car rugs rough- CC would get hot and sometimes cherry red. Please click on "Mark helpful" if you're happy with the respond. Good luck :-)
Check for leak on your wheel bearing! bad grease would leak on hot brake system (this is dangers! address as soon as possible). Please click on "Mark helpful" if you're happy with the respond. Good luck :-)
While I agree you should look over your brakes for source of burning smell, it still could be a bad CC. They give off more of a rotten egg smell though, and when you slow or stop, the fumes can waft into the car instead of being left behind.
