Sulfur (aka. Rotten Egg) Smell on '03 4Runners

[slowginjoe]

did you guys who did the tsb notice any decrease in performance? i dont want the dealership to screw my runner up.

i had mine done. i didn't notice any decrease in performance and the fuel economy is still the same.

Does anyone have a link to the PDF on this and/or any other TSBs that would apply to an 04 V6 Runner?

I had the pdf for this and now I can't find it.


Thanks in advance!

My 4Runner is a late '04 model and it also still stinks when mashing the gas pedal. I can even smell it with the windows up if I accelerate hard and then stop at a red light.

Looks like Toyota did nothing about fixing this for the '04 or '05 owners!

I had the TSB done on my 2004 and the smell is there, but not as bad as it was before. This is due to the fact that the 4Runner is a LEV (Low Emissions Vehicle). The CAT is working overtime to keep the emissions down when you mash on the throttle, the byproduct is that arse smell everyone around you smells.

That's a bunch of BS.... there are plenty of LEVs and even ULEV running around for years now that don't have any stench from the catalytic converter no matter how hard/long you mash the throttle.

Anybody know why our 4runners smell? I've never had mine fixed, doesn't really ever bother me that much

Sulfur is a component of gasoline and high levels of sulfur, slowly kills catalytic process. It would be in ones interests to use gasolines with low levels of sulfur. This is a difficult task since there is no easy way to tell. Also there are different compositions for different geographic regions and different compositions for the different seasons of the year.

I understand what your saying but what does Toyota do that corrects this smell? If it's no big deal to fix why don't they do it to begin with rather then wait until someone complains? I have a feeling that Toyota designed the 4runner to perform best with the smell and when you go in and have it fixed you compromise something else.

I'm planning on waiting till the end of the TSC term and get a new cat convertor.

It is a rather frustrating situation. This Post has eight pages! I am also going to let-it-go. I will live with it, as I do not drive with the lift gate window down, much. If I were a surfer then I

Yabedude, that is a good idea. Is that 3 year 36K miles?

I heard that what they are now using for catalyst is environmentaly safer and safer for the workers to handle but the reaction does not take care of the sulfer as well.

All very vague but I do remember reading this.

I can see your point about waiting Thanks for the heads up.

I work in the chemical field. Sulfur (S) is a odorless yellow solid found in the earth. Anything mined from the earth (like coal, natural gas, & petroleum) will have all sorts of metals and non-metals in it. Undesirables are removed from the refinery process. Parts per million (ppm) will still exist however. There is between 50-900 ppm of sulfur in gasoline. In the presence of oxygen & hydrogen (like inside the catalytic converter), sulfur will bond with these to form SO2 & H2S (sulfur dioxide & hydrogen sulfide) both are toxic gases that will smell like rotten eggs or (ass). Non-chemists will refer to SO2 & H2S as simply sulfur; but now you know better. I just thought this Post deserved some chemical culture.

anyone have this done in Canada? I know alot of American 4Runners have been done the TSB... I'm just wondering if Toyota Canada will honor the TSBs.

 

[iFORCE]

The Service Manager gave Toyota Canada a call and they said that Toyota Canada WILL NOT accept the American TSB in regards to the sulfur smell.

They said it has everything to do with the gas and Canada has a high sulfur content in their gas compared to the americans. Canada is taking steps to reduce that amount.

Once again, anyone in Canada has gotten the dealership to honor the american TSB?

I've had my 4runner for 1 year and 20K miles never did the tsb and the longer I have it the less I smell sulfur. I never drive with the back window down. I would say that I smell sulfur only once every couple of months. Kind of miss it

I heard it suggested that the new spoiler on the 05 might be there to help with the smell. If that is the case, think Toyota would eventually install that as a fix?
