I been having trouble with my car as indicated in another thread. Sometimes I do smell rotten eggs and burning wood smell when I am driving my car. Could this be a bad cat and fi so would that cause my car to stall, and loss of acceleration power?
If you're stalling and have a rotten egg smell, you might have a rich AFR. The rich mixture would be the cause of your stalling, and the unburned gas hitting the cat might be causing the rotten egg smell. There are tons of things which can make a car run rich though, all of them accessible through a search engine. Check the obvious stuff, and if you're stumped take it to a garage.
