Replying to: agnosto (Apr 10, 2006 4:04 am) Thanks to all of the posters that contributed to the sulfur SO2 issue... it makes it easier to trouble-shoot issues when information is exchanged... In conclusion, Toyota is not addressing this issue since it is a costly one (over $2k) to fix it and relies on a per case ("if you got the smell then we will take care of you"). |

Replying to: scoti1 (Apr 18, 2006 7:16 pm) Can you imagine $2,000 X 100k customers more or less = $200 millions... |

Replying to: agnosto (Apr 18, 2006 7:40 pm) Yes, but compared with the $30,000 X 100K = $3 BILLIONS they paid for the vehicles makes it small potatoes!  tidester, host |

Replying to: scoti1 (Apr 19, 2006 4:10 am) if the part number is the same then the issue is manufacture / quality control. it would be interesting to know if the part is being replaced with a different part number. if the part number is not the same, while it could also be manufacture / quality control, most likely it is expense because of superior design, tolerances, materials, size, etc etc. the number of TSBs across a range of models... perhaps its a matter of manufacturer / supplier lot related QA issues... outsourcing issues?

Replying to: agnosto (Apr 21, 2006 4:30 am) I was at the dealership today and I feel like I'm getting the run around. I was told to change gas stations -- been there, done that. The dealership has known about this problem for at least two years and I told them I would remind them every time I came in. My service advisor said he'd provide me with the TSB that acknowledges the existence of a sulfur smell but that there is no fix for it. When I checked out with the cashier she did not have the TSB and said my service advisor did not provide her with one. She said I could check with another service advisor because mine had gone out for lunch.  Thanks in advance.

Replying to: beach_girl (Apr 21, 2006 7:30 pm) >> TSB EG003-03 Introduction: Some owners of Toyota vehicles may experience a sulfur like or rotten egg odor from the exhaust system. Sulfur is a natural component of crude oil from which gasoline is refined and the amount of sulfur can be decreases through the refining process. The amount of sulfur in fuel in CA is regulated, however gasoline sold in other states can have substantially higher sulfur content. Sulfur content also varies considerably between gasoline brands and locations. Applicable vehicles: All models Repair procedure: A sulfur odor emitted from the vehicle tailpipe does not necessarily indicate that there is an issue with the engine’s condition, but is most likely directly related to the fuel. If the vehicle is exhibiting an excessive sulfur odor, the following checks should be performed: If the MIL light is ON, check for DTCs and repair as necessary If no trouble is found after performing the above check, recommend the customer try a different source of fuel. Replacement of oxygen sensors, air/fuel ratio sensors or catalytic converters will not reduce the odor and therefore will not be considered warrantable. >> That was amended with: http://www.autosafety.org/Toyota%2003-04%204Runner%20Catalyst.pdf And for the V8 there is this: TSB: EG020-04: Title: Excessive Sulfur Dioxide Odor Models: '03-'04 4Runner (2UZ-FE) Date: June 14, 2004 Google with the following to get a copy: +"4Runner (2UZ-FE)" +sulfur
