Yes, indeed, I experienced this awful almost throwing up smell like a rotten egg yesterday on stop and go traffic. I have a 2006 4Runner LMT V8 4WD with a little over 1000 miles driven so far. I will definitely call Toyota and dealership to remedy the issue...
 
I just finished talking to the Toyota dealer and guess what bad news... there is a new TSB EG004-06 that does cover the 2006 4Runners... I am going to the dealer to let them check it out...

I just came back from the Toyota dealer which he told me is bad quality of gas, but I told him I do not experience it on my other Toyota and it is the same gas... anyhow, he did not insist much and I will be replacing my dual CC in my 2006 4Runner LTD V8 4WD in a couple of days. I will post and let you know if the smell of SO2 goes away afterwards...
 
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").

The bad news is that 2006 4Runners are under the sulfur SO2 issue... The TSB for 2006 4Runner V6 is EG004-06 and 2006 4Runner V8 is EG005-06.

It baffles me that Toyota continues to use the same catalytic converter when they know it causes this problem. I have a Sequoia that was fixed by the TSB a couple of years ago. It must be more costly to modify the existing cc across the board than to just replace them when people complain. Could it be that they don't meet federal emission standards with the modified cc? Anyone in a state with emissions testing had a replacement cc put in and still pass testing? Just curious.

Oh, I am sure it passes the emission testing control and so on. The reason is what you just said and also questioned Toyota dealership and stated the same reason to be the HIGH COST over $2,000 to replace my two CCs and Toyota will honor ONLY if customer complains, so I took advantage and fixed it right away w/o much hassle...
 
Can you imagine $2,000 X 100k customers more or less = $200 millions...

Yes, but compared with the $30,000 X 100K = $3 BILLIONS they paid for the vehicles makes it small potatoes!

Yeah, but my question is, why do they even need to replace them on 2006 models? This problem has been around for a while and the new cc's have been available for several years to correct the problem. Why not put the new cc's in right on the assembly line? Something else is at play here.

an astute question. perhaps margin / profit?
 
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?

I was hoping someone could help me here -- is there an acutal TSB for a 2003 4Runner V-8 SR5 with the sulfur smelling exhaust problem? I found it for the V-6 model but not the V-8.
 
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.
