#711 of 2607 Re: Minimizing the smell [corancher]
Oct 27, 2004 (8:15 pm)
Thanks for the suggestion, Corancher. When I experience the sulfur smell, I have the rear hatch window down, usually about 3 inches. I also have the moon roof opened all the way or just tilted. I rarely have the recirculate on, unless I'm trying to cool the inside down fast with the AC. When the windows are closed all the way, I might have noticed a slight smell, but not much.
I had a 2002 4Runner and did the same thing with the rear hatch window and never had a sulfur smell...at any time over the 36,000 plus miles I put on it. But, I'm still baffled why Toyota can't correct this condition before the vehicle is sold and after 2 years of production time.
#712 of 2607 Avoiding smell if you want to keep rear window open
Oct 28, 2004 (9:59 am)
yobow1, I'm not sure if you can reliably keep the smell out when the rear window is down, but I do know of one approach to try. Whether it's for technical reasons or simply a design philosophy, Toyota has moved away from side-pointing exhausts on all the vehicles I've seen. I think that the rear-pointing exhaust is a problem for both the cabin exhaust (at least they're supposed to be exhaust) vents and for the dead air at the blunt rear end of a vehicle like this. Getting your local muffler shop to point the exhaust tip to the side may be of some help. Your 2002 probably exhausted to the side, but it also wasn't one of these extra-clean-burning new engines, so it's hard to be sure about the main cause of the problem in your case.
As for fixing the problem by reducing or eliminating the smell at the source, the TSB may be the only thing you can do. It changes the catalysts (to ones with more nickel?) and makes changes in engine management (more fuel in some situations, to avoid letting the sulfur compounds build up?) but these are not changes that Toyota is making on all 4Runners or on newly-produced ones. Presumably there's a trade-off of some kind, though it may be small.

corancher, thanks again for your input. We'll see how the TSB goes on the 2005s...or I may have to just bite the bullet.
#714 of 2607 Better Mileage, Sulfur, TSB
Oct 28, 2004 (1:11 pm)
I own a 2004 4Runner SR5 V6 RWD and have currently 18k miles on it. I recently noticed an increase in mileage both on highway and in-town. I never got more than 15-16 in town and 19-20 on highway but now this ratio is 20/24 consistently for 3 full gas tanks. This is not just computer reading but i noticed it by actuall mileage and tank fill up. I am using Shell 87 octane. Though i understand gas mileage differs in winter and summer but it was surprising to me at the end of summer. During Jun-Aug my mileage was worse. The only thing i did was use Shell V Power for 1500 miles, that gave worse mileage during that and change engine oil to Valvoline Semi Synthetic. I am unable to relate these changes to my increased mileage other than the fact, that gas expands in summer giving more efficient burning, but its not peak summer in Louisiana. The other thing i can think is the Self Learning of Computer, which optimizes Air/Fuel Ratio based on your driving habbit.
About that sulfur, I had occasional strong sulfur smell in the beginning but never noticed it again to date. I never drive with my windowns open and have kept recirculate on and off. I saw the TSB and hesitent to change CAT converter, that it might reduce my mileage.
Any thoughts on this?

Hello, I have the 2004 4Runner V6 4wd limited edition and it does not make any sound while shifting or after its engaged to 4wd hi mode or even when shifting back to 2wd. Before you take delivery, engage the 4wd and check for yourself. Bob.

Oct 29, 2004 (12:52 pm)
I think I have the same problem you are mentioning. It seems like every so often (5 or 6 times I step on the brakes) I get a ping also. I've brought it to the Dealer, and they they could not find anything immediate to say its a problem or just part of the design. I tried the Dealer's 2003 4Runner and did not notice the ping as much. It was alot more subtle. It bothers me because I can feel it. The dealer cannot find any Toyota Bulletins in Canada or US indicating any other recorded problems. I can't seem to believe this because it seems like several other people have similar problems. Is there anything I can give my Dealer to direct him.

I like your answer, but it still doesn't explain to me why I feel this Ping on the pedal every so often. If everyone on this chat tells me that they feel this ping, then I would find better things to do with my time. Can anyone tell me if they do feel this on the brake pedal.
Thanks for the explanation, but I don't think the problem is going to disappear over time.

Does anyone notice a Brake ping when they are applying the brakes. When driving around town or on the highway., it seems like every 5th or 6th time that I step on the brake pedal for whatever reason, I get a slight ping or buzz on the pedal.
Try this experiment. Put your car in park, and depress the brakes a few times. It does not have to be depressed too far. At the 5th or 6th time, you'll hear a buzz from the brake area.
The buzz doesn't bother me as much as the ping I fell in the pedal. Does anyone else feel this while they are driving around town. My dealer doesn't want to jump to conclusion as what the problem is. He says he doesn't feel it in his 2003 4 Runner.
Anyone out there might know if this is a problem or not. I also have a 2003 Highlander. The brakes feel alot better.
Please Help Me anyone
#719 of 2607 Defroster Rattle '03 4Runner Limited
Oct 31, 2004 (6:56 pm)
A few months ago there were some posts from owners who noticed a rattle in the area of their defroster vents near the windshield - a jiggling noise that seemed in some cases to be temperature related.
A similar sound has developed in my vehicle - it clears itself in warm sunlight or if I run the defroster at very warm temperature on high for several minutes. But if I start out on uneven pavement or washboard road in cold weather the rattle is very noticeable across the entire span of the windshield. Apparently, the defroster hardware (vents)contracts under cold temperature and something inside loosens up.
Do any other owners who've experienced a similar problem have a way of dampening the hardware by inserting something into the vents or spraying something that might counteract the increased play within the parts , a method that doesn't require pulling out the dash to access the defroster vents? I'd rather live with the intermittent noise than take a chance on creating a worse problem by having the dealership tinker inside the dash. Of course, if anyone has had their dealership successfully eliminate the problem by going inside the dash, I would be interested in knowing how the technician accomplished that, as well.

Mine is doing the same thing, but if you read your manual more carefully, you'll find that it's normal. As for the buzz, you're not supposed to depress brakes with ABS multiple times - you're confusing the computer.
