ROTTEN-EGG" SMELL

1998 Nissan Altima • 4 cylinder FWD Automatic • 135,999 miles

1998 Nissan Altima mileage: 135,999. The car emits "rotten-egg" smell from exhaust. Is it the catalytic converter or the oxygen sensor?

The "rotten-egg" smell is caused indirectly by the catalytic converter. The main cause is a rich mixture condition from the engine. Check the catalytic converter to make sure it is not "plugged" or restricted. Your car is equipped with a computer controlled engine management system. You can scan your computer for fault or error codes with a hand held scanner. The information will pinpoint the mal functioning components.
