Sulfur (aka. Rotten Egg) Smell on '03 4Runners

With the weather turned nice here, I've been runnin with my back window down, and whew!

I assume that since I put "Top Tier" Toyota recommended gas in it they will not give me any "it's the gas" excuse crap!

I also assume that since the TSB says until 80K miles, they will honor that (since my 03 only has 45K miles). Hopefully by then they will have the solution worked out totally.
 
that's weired, everyone is complaining about a sulfur smell! I have an 05 v6, yet i dont smell anything from the runner! Is it on all the runners? P.S. I live in FL does the gas make a difference there, because i really dont smell anything, i use the regular 87 gas!
 
2005 SMELL BETTER since tsb

just an update. this morning i leaned on the truck through a yellow light and when I came to a stop i did smell the egg smell but at a reduced( I say half or better) rate. So the fix is better then nothing. I have to see with some miles driven and some time if I can deal with it the way it is now.

I've got an answer for that smell. Cut the cats out and replace them with pipe. And remove the rear "cat o2 sensors" and hook a O2 simulator to the harness. Done. No smell. No engine light. More HP. NO problems. :D

I have friends that have done this as well on other vehicles and the problem goes away. Considering doing it to mine if it will still pass Louisiana emissions inspections.
 
No More Sulfur Smell After TSB!

I just wanted to let everyone know that the TSB for excessive sulfur on the 2005 V8 models DOES fix the problem!

I had it done a couple of weeks ago and yesterday I had a co-worker follow behind me while I did some "spirited" driving and he could smell anything coming from my 4Runner. :D

Very Cool!
 
I had the same problem when I got my 4Runner and about 2 months later, the dealer called me in and they replaced some parts per the TSB and it still smelled for a while after I got my 4Runner back, but the smell did slowly go away, however once in awhile I get that smell during hard acceleration. But it is waayyy better than it was before.
 
Re: Who will have the TSB performed?

So, who plans to have it done? Please post your results.

Personally, I plan to do it, but I don't want to be the first one at my dealership. Although, it does seem like a straightfoward job. I wonder what benefits I will receive, if any, from the upgraded 2004 Model Year OBD III logic (I own a 2003 MY).

Update: It's been about 1 1/2 years since I had the TSB performed and I noticed the stank smell is back. I'm not sure if it's as strong as before, but it's bad enough.

The Service Manager gave Toyota Canada a call and they said that Toyota Canada WILL NOT accept the American TSB in regards to the sulfur smell.

They said it has everything to do with the gas and Canada has a high sulfur content in their gas compared to the americans. Canada is taking steps to reduce that amount.

Once again, anyone in Canada has gotten the dealership to honor the american TSB?

I had the TSB done at the dealer in North Vancouver, BC on my wife's '04 V8 limited, no questions asked. Seems to have fixed the issue as her truck is FAR less stinky, if at all.
 
well i got my truck back a couple days ago after they did the fix. they replaced the whole front exhaust assembly and i have to admit that the exhaust sounds deeper and louder then it used to be. and ive noticed alittle better MPG. did anyone else notice this?
 
Any Marylanders here who had this done?

Just wondering is any one here had this done in Maryland and if you could share your dealer experience?

Took my 05 to the dealership today for an oil change and the belt noise, but mostly for the sulfur smell. Had the TSB and they just laughed at it. Pissed me off right from the start. Said they were not going to do any work unless they know there's a problem. I said why do you think i'm here, after first trying to tell you all of this on the phone. SO they checked it out, found it stinking as promised, did the rest of my work, and ordered the part for another trip back next week. Could have done it in one stop if they had'nt of been such dickheads.. ATLANTA TOYOTA just in case anyone was wondering.. Service nazi said he's only seen one other 4runner with the stink.. I said then they never drive with any windows down.. I knew before I bought the damn thing it was gonna stink. Hope this fix helps!!!!!

My Experience so far (A bit winded)

Well, I called around to three dealerships in the Maryland Area (Antwerpen Toyota, Russell Toyota, and Laurel Carmax) The service reps on the first two were a bit arrogant on the phone and I am a bit sensitive to that kind of S**t. So I called Carmax, and a Nick Bailey (service Rep) handled my call, really nice guy.

But any way; I asked him direct questions such as " have you guys ever handled this type of complaint?" I also told him of the bat not to give me that hog wash about the direct problem being the Gas I use and to try others because I have already done this in a consious manner and the problem persists.

Any way, he said bring it in, he took down my VIN and set an appointment for 7:15am 04/13/06, we'll have our tech look at it and determine the problem.
So I went, a different servie rep took me in cause he was with another customer. The lady Serv Rep read his notes and wondered if this was coming out pocket, I showed her the printout of the TSB and she read it like as if she was signing her life away (Down to the last detail).
So I waited for the truck, Nick at this point came over and told me that they could possibly have it done that same day, so i said "cool", but first he had to check with the Tech. After checking with the Tech, they did not have the parts in, so he scheduled me for Next wednesday 04/19/06.

When I was at the service reps counter signing the paperwork, the tech was there to hand the keys to nick, So I asked him if he had done anything to the computer, and he said he flashed/reprogramed the ECU, I said cool, but then he said, You know... your VSC TRACK light is on, i noticed this as i drove your truck around. I thought he said it came on and whent, so i told him, yes this will happen if you take a sharp turn and gunn it. But he said no, it is on and is still on. I told him it was not on when I brought it in, perhaps his reporgraming of the ECU or what ever he did had something to do with this. He said most likely not since this deals directly with the emmisions part and not the driving part. I asked him if this was going to affect my drive home in a ny way, or if it was going to make the truck send me home in LIMP MODE, he said no. Well, I told him and I ws very addemant about it, the Light was not on initially, whom ever drove it to the back could attest for this since the warning light is bright as hell.
We'll they told me that it could of been something that happened a while back and that just now the system decided to alert me. I don't think so. So they are going to look at it on Wednesday and run some type of diagnostic and determine what it is.

So needless to say currently I am a bit unpleased.

To be Continued. ...

DAX,

They are giving you all kinds of bullshit man. They must not have programmed the ECU correctly because the same stuff happened to me when I got my TSB done. When I picked up the truck after the Sulfur TSB was completed, I drove off the lot and not even a mile afterwards the VSC TRAC, VSC OFF and VSC light all came on. I drove back to the dealership to complain and they said that I'd have to bring it back Monday to fix since it was near closing time and the service bay was closed. Well I brought it back and they fixed it on Monday. I'll have to look at the repair invoice to see what it was but I think it turned out to be a sensor. If you do a search for my posts related to this TSB I actually typed out what was put on my repair invoice.

Good luck man.

TSB fix worked for me

My 04 sport edition V8 had a horrible rotten egg smell. The service dept where I bought it from said...but not in so many words whatever...The smell bothered me and like most of you I felt I was just stuck with it. Just so happens the in-laws were at my house...eeech...and I was killing time alone at the parts dept buying oil filters and the parts dude claimed to know averything about toyota so I threw my ques at him. He never heard about it but looked it up on the computer and found a TSB which states to replace the cat convert with a different conv and reprogram the ECM. So I had the parts guy print it out and I looked at my VIN and I did not think it matched up but made the appointmnet anyway. I told the service guy I need the sulfer smell fixed and he smiled and started to tell me its the gas as I handed him the TSB his parts guy printed and he said not a problem sir what day would you like this done...So Jan 18 06 it was in the shop and not even a hint of oder since. I have had all the windows down and stomped it throught the gears nothing but a cool breeze. I am a car enthusiast and even I cannot tell any difference in power. If I am not mistaken the emmisions warrenty is around 80.000 miles or so. I believe toyota needs to recall this but wont because it is to expensive to do this for everyone. I also believe dealers pay for warrenty work themselves unless it is a recall. So Toyota doesnt want to pay for a warrenty and dealers dont want to pay for the TSB that is why it is so hard to find the answer to the problem.

P.S. I was behind a 04 4runner last week going up a hill and man his 4runner stunk pretty bad...poor sap.

Got the truck back today and so far the only smell is the new pipe... Was so nice having ALL the windows down for once.. My advice is for everyone with the stink, go and make them fix it...
 
He aint stinky no more!

Well, picked up my truck from the CARMAX service dept in Laurel MD yesteday after work, and let me say - he aint stinky no mo!-
all I could smell was (like someone said here) was the fresh smell of welded pipes, after the burnoff I could smell nothing but fresh air coming from the back.

As I mentioned above, the VSC TRAC/VSC OFF warning lights came on, well, after reading this post I called the service dept and told them that it was common for the lights to come on after flashing the ECU. Well they took care of it and no more warning lights.

So, I shall print and carry a link to this thread to hand it out to the average 4runner owner to come here and read the posts regarding the smell. May be this summer we all can see more 4runners with all their windows down and more smiles :D

Later

Maybe I spoke to soon??? Had the back window down at lunch today and when i got on it hard, the smell was there, but not as bad as before, but still there... Guess i'll have to watch those hard starts with the window down.. Will keep ya posted!!!
 
Gunning It

Same here, the smell only shows up if you gun it, but I can say that it does not happen all the time as it did before.
 
I have a 2003 4Runner V-8 4WD with the well known stinky exhaust. Toyota is not helping. I found the TSB for my model year and engine size but my VIN is not listed - they all appear to be 400 or 480 series -- my VIN is a 300 series:JTEBxxxRx300xxxxx

Is my 4Runner involved in another TSB?

Thanks,
BG
