After reading post after post I came up with some possible answers to some issues. Some people are saying theres does not stink. To those maybe they have had the tsb work done already. There SHOULD be a sticker under the hood if this is the case. Then there is the issue of some still stinking after TSB work. According to the TSB dated June 14 04 the converters are still being used on new production vehicles and are the replacements but this may have changed since then. One way to find out is to call and ask for part number to cat at least for the V-8. According to TSB the same cat is also used as the replacement and the superseded part number is to be used if the customer complains of the smell. Maybe they are better at emissions so they continue to use them unless theres a complaint. To quote the TSB "The original part (17410-50360) is CURRENTLY used in vehicle production and is STILL available as a service part. The repair part (17419-50460) SHOULD be used when the customer complains of sulfur dioxide odor". So maybe inadvertently when the parts guy is ordering the replacement he is ordering the original again and not the upgraded. Just looked at the May 27 04 TSB for the V-6 and it says the same thing other than part numbers. By the way I just got an 03 4runner and it stinks and has no TSB sticker under the hood so I will be looking into having it fixed and making sure they order the right part. It is my first foreign vehicle and I am quite proud but have a problem when others complain about it's smell. I can't very well brag it up when there U.S. vehicles at least don't stink.
