The sulfur smell is due to poor exhaust design. The muffler outlets are not extended far enough out to dispense exuast from under the vehicle. I will be trying pipe extensions ... 2008 LS460 38,000 Mi...
View 12 RepliesI purchased a 2011 Chevrolet Impala last year with 14,000. When the car reach 26,000 I begin to smell a very strong sulfur smell coming from the exhaust. I took the car to the local Chevrolet dealer and was told that the particles in the catalytic converter begin to break up at about 26,000 mile and the result is a sulfur smell.
I didn't believe that all Impalas had this problem. So I took it to the Chevrolet dealer in the next town where I personally know and trust the maintenance chief. He put his two best men on the car and could not find anything wrong. I was told to try another gas station which I did but it did not work. I now have 31,000 miles on the car and the smell is very strong coming into the passenger compartment when stopped.
Just put a dual flowmaster exhaust on my truck, a week later my engine light came on. I also smell a sulfer smell and the truck seems to sutter when in gear at a stop, and also hard to start at times. What this could be!
View 9 RepliesI have been noticing this Rotten egg/sulfur exhaust smell I have been getting for the past 2 months. So far it only happens when the engine hits 3000rpm or higher.
View 9 RepliesMy 2003 F150, 5.4L has been having some rough idle/misfires issues both at idle and under load.
I have fixed one big vacuum leak, replaced the PCV valve, new sparkplugs, seafoam and heet in the gas, replaced fuel filter, tested the fuel injector resistance. Coolant levels have not changed. The truck burns about a quart of oil every 1000 miles or so. The white exhaust is heavier than condensation, but it comes and goes. The rough idling comes and goes as well, and it usually happens under load and the CEL flashes.
The codes I get are random cylinders, po303, po308, po171, po174 were the most recent but there have been other cylinders as well. I clear the codes after each attempt to fix it and they come back different.
I notice that there is a small exhaust leak that drips water just behind the engine, and when I shut down the truck a lot of water will pour out of an area just behind the cab on the passenger side as well as out of the bottom of the muffler (small hole, looks drilled).
Usually the rough idle occurs after filling up the tank, but from different stations so I do not think it would be watery gas. I use Heet every fill up as well. Also, there is a sulfur smell after the rough idling occurs (catalytic converter?).
So with the warmer weather, I've finally had a chance to drive my car spiritedly (2015 IS350). However, I noticed that under full throttle for about 5-10 seconds, I get a sulfur smell after I let off the gas. I thought maybe it was the gas (I've only put in Shell V-Power 91 in this car) so I drove the car until it had less than an eighth tank, then put in Petro Canada Ultra 94. So far, I've driven about 80 km on the new tank but I still smell a sulfur smell after hard acceleration.
I never noticed this smell last summer, so I assume it's related to something that's changed. So far my car is still 100% stock so the only culprit I can think of is gas. It is possible that I never noticed it before though because you can't smell it when the windows are closed with AC on, which is usually what I do in the summer.
It could be the "winter blend" gas that gas stations have right now?
I have a sulfur smell in my 05 since new, it now has 23k and is a little better now. The dealer said to switch gas stations. I haven't noticed this. I notice it going up hill with the top down sometimes but mainly after parking it in the garage. The dealer said it would not hurt the car. I worried that it is running too rich and damaging the coverter, plus it is annoying. I love the car but it sure isn't perfect.
View 11 RepliesI have a 2009 lexus es 350. Its my baby since new. I have around 75,000 miles on it. Recently when I start the vehicle I noticed a heavier than usual exhaust smell, with some very very light white exhaust. The car seems to drive fine in every way.
View 2 RepliesAre my cats bad already? Have the rotten sulfur smell when they get on it? I have headers installed with stock exhaust, 08 with 24k miles. Smells real bad when I get on it. I have the Magnaflow 59955 metal cats coming in tomorrow.
View 13 RepliesHave a 2003 LE V6 with 95,000 miles on it. It is stalling at stop lights and when pulling into the garage where the smell is noticed. Our mechanic has been unable to replicate the situation.
View 2 RepliesI have had my car since it rolled out of the plant. Along with other issues one of the most bothersome is a strange smell when I accelerate above 60 mph and it gets worse between 70 and 80mph. Additionally, when I pull into my garage after having smelled this smell on the freeway, I can smell it on the outside of my car.
My car has been in and out of the Ford dealership every month for many issues but this particular issue each time I bring it in. It wasn't until my most recent visit that they told me that with new cars one can occasionally smell this when undertaking a hard acceleration. Then I was asked if I have visited websites or asked questions on the web about this smell. But until now I didn't know what the smell was.
I have been on websites that say this is normal for new cars but if the smell gets worse over time there is a problem with the carburetor. I need to know exactly what to tell the Ford dealership when I go in again have them fix this problem. I also would like to know if this smell I smell is harmful to my children and I. And is it leaking the smell all the time but it is just over a certain MPH that I can smell it.
I own a 1996 Buick Regal with 132k miles on it, 3.1L six cylinder. The other day I was doing some general maintenance and noticed that the exhaust smelled like sulfur (rotten eggs). Now, I am loosely familiar with the causes of such a thing but not well enough to diagnose it properly the first time. The car has been idling rough since I got it (almost a year ago now), I have a feeling that it could be the O2 sensor causing the rough idle and the sulfur smell but I am not completely sure. I should have one of those fancy three-part injector cleaners done?

I drive a 2007 Toyota 4Runner. Recently the weather has been nice enough to drive with the windows open. I've noticed a very strong ammonia smell from the exhaust - so strong at times, that I have to roll up the windows and use the a/c. I use Shell gas with no ethanol, but it has a nitrogen additive. Is it the gas I'm using, or is there something wrong with the vehicle? It's definitely ammonia, and I can only smell it while I'm driving.
View 12 RepliesI have a 2003 SC430 with 170,000 miles on the odo. It runs great, but the exhaust smell is killing me. I'm pretty sure it's normal for an 11 year old car, but I want to eliminate it.
Do you know what part or part(s) I might be able to replace to eliminate the foul smell?
I have a 2014 RX 350. I have noticed an intermittent issue with exhaust smells coming into the cabin when the car is on recirculate and I am at highway speed. It happens when I am first accelerating after I've entered the freeway. If I get the odor, I can make it go away by briefly hitting the recirc/fresh button to bring in fresh air for a few moments. This doesn't happen driving around town.
View 5 RepliesI have a 87 F250 with a 302. Every time I drive it I smell like exhaust. Doesn't matter how short or long the trip, but the longer the trip the stronger the smell when you get out. I found 1 loose manifold bolt and tightend it, but no difference.
View 13 RepliesThe truck in question is a 93 F-150 X/cab 4x4, has 5.0 5spd. So yesterday i replaced my exhaust with pre made magnaflow "y" pipe/cat with a flow master 44 then new pipe all the way out. When i start the truck up this morning to let it warm up a little it started to give off a funny smell almost like brakes/electric burning smell. I was wondering if this is common for new pipes to burn off any oils that may have collected on them from the factory. I look under the truck and nothing is touching the exhaust, but the shiny new pipe is starting to change colors. So do you think it will go away in a short time? I have to an appointment about 30 miles away on the freeway think this will burn off?. BTW there was no smell prior to the exhaust change.
