I have a 2005 Mitsubishi Endeavor with 76000 miles on it. A few months ago I noticed a rotten egg smell coming from my car once I returned home from driving. It didn't happen very often, so I didn't worry about it. It's still happening intermittently, but more frequently than before. My gas mileage is still the same as it was before. I can't tell if I've lost a little power going up hills or if it's in my head since I'm looking for it. My check engine light isn't on and hasn't been on. I'm noticing it more now if I sit idling for a while in traffic with my air conditioner on. We called the Dealer and he said that if the check engine light isn't on then it's not the catalytic converter. If the fuel mixture is too rich, what would cause it? HELP!
have the same problem?
