5th & 6th Generation (2002-2006 & 2007-2011)Toyota Camry Discussion for years: 2002-2006 & 2007-2011
Topics of discussion range from fuel economy, safety, modifications, performance all involving America's favorite family car, the Toyota Camry.
Whenever I push the gas pedal harder I get this rotten egg smell. Does anyone know what that problem is? Could it be the muffler or the brakes because the smell is coming from in front of the car.
True using a quality name brand gasoline. It will take some time to burn the deposits out of the catalytic convertor, maybe many tankfuls. They have accumulated there and that's why you are getting the smell. I can't remember exactly, but I think it's either sulfur or phosphorus.
Back when cat converters were first added in about 75, darned near every car's exhaust smelled like rotten egg until they warmed up and leaned out the mixture. On a similar note, the cat converters on a lot of cars would start popping, sometimes real loud when you parked the car and turned the engine off. Had a friend with a Datsun 240Z and the first time I rode in it I thought it was going to explode. Don't smell many new cars with a smelly exhaust any more, nor do I often hear cat converters poping as they cool.

The only thing in common with the old convertors and the convertors of today is the job that they do. They have changed extensively. Fuels have also changed extensively since that time period.
now that you mention that I often hear popping while i'm driving. I always thought that I was running over something. So what should I do, its a se v6 so should i use high octane gas or replace the exhaust?

It's sulfur that build up in the convertor. Phosphorus smells more like burning rubber also, not eggs.

Change to a different brand of gasoline for the next few tanks. That means stick with that same brand for those tankfulls. Make it a major brand. It is excessive sulfur in the current brand of gas that you are using that is most likely causing the smell.

Am I correct in inferring from this, that you're saying it's better in the long run to stick with the major branda of gas, rather than filling up with the unknown cheapest?

Not necessarily. Most gasoline in a given area is the same; it's usually the additive package that is different. I buy the cheapest gas that meets the octane requirements of my cars. Lately around where I live lately that's been Shell or Mobil, both major brands, but I have not been affraid to try an off brand. That said, since he is having a problem that usually stems from the gasoline he is using, he has no other choice but to switch. This may or may not help him, but it is the most logical place to start.
I noticed the exact same problem today...rotten egg smell when I accelerate and RPM's reach around 4000-4500. This is a brand new V6 Camry SE with only 650+ miles on it, I also think the engine vibrates way too much and isn't as quite as I think it should be.
The first tank was from the dealer so I don't know what they put in but the tank I poured was Shell 87 octane...
