The smell is absolutely NOT causing damage to the engine. The smell is from a reaction to material in the catalytic converter. |

my sulfur smell goes away when I use mid-grade gasoline. Switched to mid-grade shortly after purchase after a discussing it with another 4runner owner who had the same problem. As long as I burn mid-grade, the smell does not occur. As a test, a few weeks ago I filled up with regular and the smell returned. Going back to mid-grade solved the problem for me.

Replying to: md4runnerman (Aug 19, 2004 9:57 am) I beleive that TOYOTA MOTOR COMPANY should pay attention regarding this Sulfor Dioxide Complain. They need to issue a recall for those affected cars. |

I have filed the Lemon Law in the state of Florida because of the sulfur smell inside my vehicle. Toyota replaced my catalyst converter because I had the sulfur smell at low speed. It was replaced on 6-24-04 on a TSB EG020-04. I still have the smell inside the vehicle when I accelerate to a high speed and then let off on the accelerator and come to a steady speed. In about 15-20 seconds the cab fills with exhaust. The sulfur smell is carbon monoxide. Carbon monoxide is odorless, the sulfur smell is a detection warning of carbon monoxide inside the vehicle, not outside, where it belongs. I have had the vehicle back to the dealer three more times to fix this problem, to no avail. Following the lemon law procedure, my first arbitration was denied, based soley on a road test. I had used their recommended fuel and it had helped, but not solved, the problem. During arbitration Toyota recommends only BP Amoco gasoline to help with the sulfer smell. They acknowledge that it's a fuel problem. They are asking me to mask the detection smell that warns me of the presence of carbon monoxide inside the vehicle. At the end of arbitration Toyota told me that other manufacturers are experiencing the same problem. The arbitration company's is NCDS (National Center for Dispute Settlement), which is hired by Toyota. Now the office of the Attorney General takes over for a new arbitration hearing. This is a very serious health hazard.......I will keep you posted.

I don't understand at this point how your car can be filling with carbon monoxide (even though I certainly believe that your car stinks inside) without you being too dead to post, or, if not, at least seriously impaired with typical CO poisoning symptoms. How have you determined that you have CO in your car's interior? The reason I ask is because that's a pretty startling claim and should therefore have startling evidence.

Well, maybe not. I won't consume bandwidth by recapping all the previous discussions here, but would encourage anybody who cares to read extensively in this discussion. In summary, today's engines burn so clean that the old carbon monoxide problem (due to incomplete combustion) doesn't usually exist. It's a stink nuisance and would probably be improved if Toyota went back to the side-firing exhaust they used to use. Stink is probably coming from the rear cabin exhausts, so you can often avoid the stink by simply leaving the system on fresh (rather than recirculate) and having the fan on at least the low setting. If the stink is a problem, get the TSB(s) and keep leaning on your dealer and, by all means, complain to Toyota too. This kind of thing shouldn't be happening, but it's not unique to the 4Runner or to Toyota. |
