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 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?).
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.
I 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 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 RepliesI have been having a strange engine moan now for a few weeks. It happens on light acceleration before the truck shifts at all speeds. It can be faint or extremely loud and I can keep it doing it if I keep the throttle in the same spot when it starts. Also now lately when it does it I can smell exhaust in the cab. No codes are being thrown...naturally

View 11 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 have a 2005 F150 4X4, has 43,000 easy miles on it. When I started the truck I notices white smoke come fron the exhaust. It was a cool morning and the truck was sat for 24 hours, I have read some post about how that could be the reason. I was also told that adding a quart of lucas in place of one of the (motorcraft synthetic) quarts.
View 3 RepliesI own a 05 XLT Screw 4x4. Dual rear shock set up? My truck drops in the rear when I load up my quads and attach my trailer. I could do an add a leaf but thought a dual shock setup might look and perform better. I am going to add traction bars also because I get a lot of hop when the bed is empty and I'm in the sand.
View 6 RepliesI am looking to add a new exhaust to my 05 F150 SuperCrew and am stuck between an MBRP and Magnaflow. I think I want to go with a S.I/D.O setup. Any opinions on either brand or are they basically the same?
View 9 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 RepliesSo 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?
Looking to put dual exhaust on my 2010 F150. Which muffler. Flowmax or Magnaflow. Do not want it very load. Looking a little smooth churn like the Mustang. As you know ford is very distinctive and I want it to be heard to some degree.
View 14 RepliesI 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 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?
View 6 RepliesExperience a strong smell when WOT? Seems like every time I put my foot down hard through a couple of gears it stinks for a few minutes. The car only has 28000km, fresh oil change and running great.
View 5 RepliesContemplating getting exhaust on my 2.5L SE. Haven't decided on what type of muffler, but I would only get one (1 in with 2 out). Two questions:
First, I'd like to get the bottom black piece from the V6 Passat with two cutouts for the exhaust tips. This way I wouldn't have to cut or modify mine -- just swap them out. Can you just swap out the black plastic or is the bumper just all one piece?
Second, on the right side bumper -- under the frame -- there is large cover. On the opposite side it's where the tailpipe is and what looks like another muffler? What's under this cover?
My bad for not knowing the technical terms for these parts.
