I have an 04 SR-5 V6 2WD and I smell it when accelerating up the freeway on-ramp. (i live in socal)

I got this from a thread on tundrasolutions.com

Looks like Toyota finally is admitting that there is a problem with the release of TSB EG015-04. They are replacing the cat and reprogramming the ECM.

Toyota does not notify owners when a TSB is issued, only if it is a Campaign (Recall) or a Customer Support Program.

June 14, TSB EG020-04, EXCESSIVE SULFUR DIOXIDE ODOR, 2003 – 2004 model year 4Runner vehicles equipped with the 2UZ–FE engine produced BEFORE the Production Change Effective VINs listed (see the TSB for the VIN #'s).

I asked them about my late 03 4Runner and they are saying that changing the converter has no effect on the smell. They don't want to deal with it. Did anyone notice a reduction in the stink with a changed catalytic converter?

It is more than replacing the Cats, it also includes a reprogram of the ECU. Combined there is a drastic improvement. I don't think they have a lot of option when it comes to doing this. If you are having the problem with the odor, then they are obligated to correct it.

You may be running into the summer problem. In the auto repair business summer is the busy time of year. They are probably trying to discourage warranty work because it doesn't pay as much as they can charge customers coming in the door. I bet you stop by the first week of Januaray and they will want to perform every TSB they can find on your 4runner.
