Re: Who will have the TSB performed?
I'm not sure it is an upgrade. It is a fix for a problem and since it was not originally designed like that it may actually be a performance downgrade.
I'd like to know the specifics of the ECU recalibration and exactly what it does and how it will affect performance.
btw I don't have the smell.

sulfur smell
hey guys, i just had my runner serviced for this sulffur smell. I had no clue there was a whole mess going on. i bought the car in march n didnt get to drive with the windows down until early may n is when i noticed the smell. i dont drive the car that much so i thought it was the breakin in smell. but this was way too strong. and like it says in the forums happens when i accelerate n have the back window down. I called toyota dealer they told me they never heard of this, and had the car inspected, they changed some pipes and some oxygen sensors. i got the car back before yesterday but havent been able to drive it yet to test if the smell still there. hope not cus it really sucks.

The Stink Is Gone!!
Dropped my baby off last week at the dealer. Emailed them the "pdf" that i got off of this site, stating the fix from Toyota, under warrantee, and have been driving a Stink Free vehicle now and must say...I am Thrilled!!
They replaced the catalytic converter.
Feel free to drop the rear window down and take a deep breath of Fresh Air at anytime now!!
Thanks T-4Runner.Org!!

so to all the v8 owners out there who's had the sulfur tsb serviced, do you notice any loss in performance or other deviances because of the reprogrammin/new cat.conv. ?

just called the local dealership here and they knew nothing about the new june 14th 2004 tsb calling for the fix. :bs: i guess i will make an appointment, take a copy of the tsb with me and pray for the best!

Mine is still in the shop
Dropped of at 7am at Stephens Toyota in Bristol. This appointment was scheduled. Regular service oil change and cabin filter, plus a look see at a pulsating brake (rotors being turned), sunroof rattle (completed) and the sulfer smell.
It's 4:50 right now. Still no word on if they are going to flash the ECU and replace the catalytics. I got a call at 2:50 that the technician could't reproduce the problem (sulfer smell) and they can't repair it if they can't duplicate it. I told the service advisor that I would be happy to accelerate and slow down with the side windows down with the tech as a passenger.
I think they will try and fix it.

Re: Mine is still in the shop
Well, it's all fixed except for the sulfur smell. They didn't do anything. I don't know who test drove it but they probably drove with the windows up. I will "demonstrate" the problem on the next oil change.
:
I didn't hear the sunroof rattle on the ay home, and the brake pulsation is gone as well. I didn't realize changing the cabin A/C filter was so expensive. $43 with labor. The part was only $20. Next time I'll do it myself, like tire rotations and greasing the drivetrain.

which maintenance service was this for, 15 or 30k?

Around 13,000 miles
This was at almost 13,000 miles. Now I wonder if the rotors will need replacing before 100K.

Re: Around 13,000 miles
I'm surprised that your rotors were warped (I assume was the cause of the pulsating brake) so soon (13,000 miles). Now they have less mass and are liable to heat up sooner and to a higher temp. As a suggestion, I would think that it is very important that you use a torque wrench when tightening the lug nuts.

Re: Re: Around 13,000 miles
Yes, I did use a torque wrench at 7800 miles to reinstall the wheels when I rotated them. The problem didn't surface until a few months ago, around 10,000 miles. And I tightened in a torque distributing pattern also.
My assumption is that there were unrelieved manufacturing stresses in the rotor steel. Over time, the stresses warped the rotor. Rotors are cast, then machined, then they get repeatedly heated and cooled on the truck during braking. If there are grain structures in the steel that relieve in use, the rotor can warp.
