#853 of 874 UPDATE: Sulfur from 2003 4Runner [bob443]
Jan 24, 2007 (12:08 pm)
Hi this is really bob443, I started this over three years ago, but I did a login id and password that I do not remember. Any way lets update everyone on what the situation is with Toyota and your options with the sulfur mell:
Basically there is nothing you can do. It's a matter of them using a different Catalytic converter (a cheaper one). I took this trough the Arbitration court and lost. I tried hard and based my issue with the fact that the smell was putting my child's health at risk. It didn't work. So here is what you can do:
1. Buy the attachment that pushes the exhaust pipe out to the side and then it won't come into the windows as bad.
2. Your best bet if you don't like the smell hook up your car to run E85 and you will smell french fries instead.
3. Buy a Honda.
I don't mean to be harsh but I am so fed up with Toyota and I have since sold the 4Runner.
Good luck, sorry I don't have any good news to report.

There was a TSB that called for the dealers to replace the Catalytic Convertor and reprogram the ECU.
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).
see message 808.
Factually, Toyota had issues with a number of models with CAT Convertors that were probably defective.

Oh ya we took it in and had the Catalytic Convertor changes and re programed but I am just a consumer who can't tell one Catalytic Convertor from the next but it looked like they put in a new one but it must have been the same type that they are using when they build the 4Runners because the smell was still there. That's when we took it to Arbitration and lost.

did you do this BEFORE the new cat was available? replacing it with the same CAT and just doing a reprogramming probably wouldn't help.
did you try taking it to another dealership? because the new P/N covertor and the reprogram should have helped you.

Is there a VIN search I can do? Driving with the windows down is tough in MI when it is 20 degrees out.
#858 of 874 Transmission on 06 4 Runner not engaging.
May 02, 2007 (11:00 am)
I have an automatic 2006 Sport Edition 4 Runner. Most time when I shift the gear to drive, the transmission takes awhile to engage; It's let driving a manual when you're trying to push the gas and it just sits there until you release the clutch then all of the sudden (4-6 seconds later) the transmission catches. It's been a year since I have the car and it is happening more often and now takes even longer for the transmission to engage.
I had this problem ever since I bought the car a year ago. Every time I take to the dealership, a mechanic will drive the vehicle and he does not see or feel the problem. They plug a computer to it and get no reading. It's getting very frustrating because friends who ride with me are experiencing the problem and the dealership don't. Not sure what to do or if anyone else is experiencing this as well. Sounds like I have a bad transmission but cannot prove it.

how many miles on it? it's possible it needs the transmission fluid replaced, specially if it is dark in color.
it's also possible you have a lazy / slow solenoid valve assembly which controls where the fluid is ported. my thinking is. they won't replace that for you?
have you brought it to another dealership? should be a warranty item right?
i feel for ya.
#860 of 874 4Runner sulfur smell
Mar 09, 2009 (1:09 pm)
I have a 2008 4Runner and I get the sulfur smell mostly when I drive with my sunroof and rear window open. I am now getting the smell when using the defroster. Toyota dealer told me there is nothing they can do about this, they are aware it is happening but there is no fix. Service manager told me to "just drive with the windows up"! I refuse to alter my ways of utilizing the features of this vehicle and my comfort just to make it easier on the dealer!
#861 of 874 2008 4Runner Limited - Terrible sulfer smell
Aug 19, 2009 (8:31 pm)
I see from the previous post that this is not the first time Toyota has had a problem with their CC's. I bought a new (08) toyota 4runner Limited V8 in March with 13 miles, now has about 11K. She had her first oil change after 5000 miles (as recommended by the dealer) then a month or two later I noticed something strange. When I go from slow to fast at a moderate pace (passing cars, cruise control engaging on a hill, merging from off ramps onto highways, etc.) I get a foul stench inside my car that smells like a mix of ammonia and sulfur. For those who are really quick you put those together to equal pee and poopie. The smell is terribly strong at first then eventually goes away.....until I need to accelerate quickly again.
I have tried various scenarios like accelerating with the AC and the re-circulate on and accelerating with the AC on and the re-circulation off. I have also tried both previously mentioned methods with the AC off. Windows open, windows closed, you name it..I've tried it. I mentioned it to my mechanic before her recent 10,000 oil change, when I picked her up he said everything he checked the exhaust and everything was okay.
Has anyone had any luck having the dealers remedy this since the last post? I'm due for an inspection in September, if I point my mechanic in the right direction, he sees a problem, is there a chance it won't pass? If it does, I was planning on bringin the failure slip to the dealer. Any info would be greatly appreciated. Thanks!!

I seem to remember reading my owners manual that it cautions against driving with the rear window open because of fumes entering the cabin. We have a 07 sport edition with V8 and have never noticed sulfur smell.
good luck with resolving the problem.
