Grand AM :: Car Running Rough With White Smoke And Strong Gas Smell Coming From Exhaust

My car was running rough, with white smoke and strong gas smell coming from exhaust. It died out on me a few times as if it was not getting enough acceleration. Well, I coded it and said misfire cylinder 3 and 4. I also tried to shut down 3 and 4, but did not shut down. I switched 3 and 4 with 1 and 2, still did not shut down cylinders 3 and 4. Engine coils are good, engine module was tested and passed twice. Ok, fuel injectors 3 and 4 were leaky and I changed them out. New spark plugs and boots. New oil and filter..(There was gas in my oil and oil in my air filter.) With the new parts....my car sounds soooo much better!!! still a little rough, does not bog down, but it still has the strong gas smell and white smoke from exhaust..(gas smell soo bad I had to open all doors to the garage!!) What else could be wrong?!?! I'm getting frustrated!! It also has NOT ever over heated, does not run high.

Jeep - Liberty :: Strong Exhaust Smell Coming In Through The Vents

For the last few months, I've had an annoying problem with my 2003 Liberty. If I'm driving the car with the blower on (i.e. when it's cold out), whenever I stop the car and am idling, I get a very strong exhaust smell coming in through the vents. If I turn the fan off, the smell goes away. At first I figured it was due to being behind other vehicles, but now I've noticed that it does it all the time, even when there's nobody else around.

I brought the jeep into a shop a couple of weeks ago to deal with a separate CEL issue (evap leak - fixed by replacing gas cap) and I asked the mechanic to look for an exhaust leak. He said he didn't see any readily apparent problems with the exhaust line.

I'd like to deal with this because it's not very pleasant to inhale exhaust fumes through the vents. I intend to take it back in - but is there anything I can tell him (i.e. like, a particular part of the exhaust system to inspect more carefully) that will solve the problem?

Impala - Chevrolet :: 2011 - Strong Sulfur Smell Coming From The Exhaust

I 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.

Ford 6.7L Power Stroke Diesel :: 2012 - Exhaust Smell Coming From Truck - White Smoke

Today I drove to dinner in my 2012 6.7 with no problems then on the way home my brother said he noticed my truck was white smoking quite a bit and he said there was a very strong exhaust smell coming from my truck ( he was in his car behind me) I ran a diagnostic test and what came up was code P0401 (I believe that's right). Need to figure out what is going on with my truck before I take it to the mechanics and get charged up. The truck still has DPFs in it just has a DPF back exhaust and has a AFE cold air intake running on a stock tune. However I do have the DPF deletes and EGR delete sitting in my garage just haven't gotten them on the truck yet.

Passat (B5) :: Strong Exhaust Smell Around The Car And In The Cabin Except When A/C Is On

There is no noise that would indicate a hole in the muffler, just the exhaust smell. I'm wondering if the catalytic converter is going out? If it is the catalytic converter, will it strand me on the highway eventually?

Elantra MD (2010-15) :: Intermittent Strong Exhaust Smell

I'm going to take my Elantra in to get it checked. My Elantra is a 2013, got it in March. Over the last few weeks, I would say, on 4 days or so there has been a STRONG exhaust smell. No smoke, nothing else but a smell. If I'm pulling into the garage with no idling, just pull in and park, I get out and the smell in the garage is very strong. I have to leave the garage open for at least an hour if not more to air it out. The cab ends up having a light smell inside the next day still.

If I'm parking outside when I get out I can still smell it, but not quite as strong, because I'm not in an enclosed area. I don't think it's an exhaust manifold leak, because I don't hear the popping. My best guess is it would be in the tail pipe area pre-catalytic converter, or in the catalytic converter if it is in fact an exhaust leak.

Touareg :: Ticking Under Heavy Acceleration And Strong Smell Of Exhaust In Cabin?

Not long ago my wife said the air recirc doesn't work any more on our '04 V8 and I had to admit that I agreed. After a little investigative driving, I noted that heavy acceleration (or uphill climb) causes V8 to tick (can hear it reflecting on passing walls, for instance) and strong smell of exhaust in cabin.

I thought it might be a manifold/exhaust system leak causing the noise and the exhaust smell. Seems to be only when driving aggressively or climbing. Soonest the local dealer can see it is 7/21 (16 days from now). You think it safe to drive?

Camry :: Strong Exhaust Type Smell In Cabin After Warm Up And Vents On

I just had a blown motor swapped with a used engine with around 50,000 on it in my 2002 Toyota Camry LE 4 cyl.

After driving the car enough to warm up I turned the vent on and in comes a fairly strong exhaust type smell.

I have driven the car for a little over an hour since the motor swap.

The car is driving fine with plenty of power and no sputtering or rough idling.

I just called my mechanic and he seems to think it is due to the oil that is present on/around the motor/exhaust from the swap that is burning off.

Caprice :: 1984 - Car Starts But Sounds Horrible

I got an 84 caprice that was given to me by my uncle. The car starts but sounds horrible. When I drive it I have to mash on the pedal to get it to stop missing. Once I get her going she rides fine but from a dead stop she putters a lot. Also I have to stand on the brake and its still not stopping fast enough. It has the stock 305 with the electronic choke rochester quadrajet.

Ford 6.7L Power Stroke Diesel :: Strong Exhaust Smell On Cold Start?

We've had a run of -20 to -40 weather here for the past few weeks.

A few weeks back I noticed that when I climbed into my truck after command-start warm up for 10 minutes, and I could smell strong exhaust.

I figured it was hopefully the wind, or an isolated event.

Over the past few weeks I've used my truck for 3-4 more around town runs and every time I warm it up I get the strong exhaust smell. It's that rich, eye watering, sickening exhaust smell. I also notice a small yellow frozen puddle under the exhaust tips that wasn't there before.

It's bad in the cab, but even walking around outside the truck and the smell is sickening. I actually just started the truck and I could actually smell the exhaust smell faintly, from inside my house! This has never before occurred. Prior to this, a person could hardly tell it was a diesel by the smell of the exhaust.

Once the truck is up to temperature the smell seems to disappear, or at least lessen.

Ford Ranger / B-Series :: 1994 - Running Rich / Strong Exhaust Smell

1994 reg cab 4.ol 13ok.. my wife just got it, been doing some small things like replaced dome light, replaced cargo/third brake light, truck starts and seems to run ok. but i get a headache in it which i believe is carbon monoxide, has a leak or something? i text previous owner, he said he replaced 02 sensors, but didnt say if they were bosch or a good brand.. also trucks has a oil pressure and coolant temp gauge fitted on by the gear shift as the dash gauges for those functions are out. Does this mean the CTS may not be working and affecting fuel/air I do not know these trucks i only just found out what this strange silver looking thing was it is the IAC, I Believe, then there is this black plastic vacuum type cylinder by the passenger side firewall, what is that? and right against the drivers side fire wall is a small reservoir type thingy, is this something to do with ABS? i do have an ABS light on, was hoping it was the bulb out on the third brake light or something quirky like that no such luck its still on after starting engine. but i am concerned about this running rich/strong smell as we really cant take it far as is it, its dangerous, may have to get a smoke test? Just got the truck, trying to get caught up..

Caprice :: 1984 - Possible To Remove Speedo Without Pulling Cluster?

Have the usual winter squeak on speedometer, and twice I have tried to pull the cluster.

First time could not remove cable because I was not aware it's clipped to prevent turning. The second time I was not able even to get my hand in there to unclip it and unscrew.

So is it possible to remove just the speedometer head and leave the cable in place - there is an image in the shop manual showing that, but no "instructions"?

GTI 337/20th Anniversary :: Strong Gas-like Smell Coming From Engine Bay?

I recently had a turbo installed, everything went well, car runs very smooth considering having just upgraded the turbo. However, I keep noticing a strong smell coming from the engine bay. Kind of like a gas like smell or some chemical. At first I thought it was the loctite we used to put the gaskets in place burning off or the coating of the turbo but it has been a week and it still smells. I do not have a check engine light, my vacuum is right on the money, I am boosting fine, and my temperature gauge hasnt moved. What could this be? exhaust leak maybe?

Golf/GTI VII :: Strong Mildew Smell Coming From Vents?

Mk7 GTI, currently at 5k miles but strong mildew smell coming from the vents.. I know the cabin air filters will last at least 15-20k miles.

I read before that the condensation hoses were sometimes installed incorrectly leading to run off inside the cabin. Can that be it?

Accent LC (2000-05) :: Strong Odor Almost Like Diesel Coming From Exhaust

I have a problem that I cannot pinpoint. For at least 2 months now, I have noticed a strong odor almost like a diesel coming from the exhaust. I replaced the plugs, wires, air filter and cleaned out the throttle body but it remains. No check engine light and runs smooth. Also, noticed a significant loss of coolant from the overflow bottle. Filling it every 3 days. Took it out to inspect for holes or cracks and nothing. Not sure if all these are related. Every oil change the used oil smells like fuel. I was thinking rings going bad but don't think that would solve the coolant loss which is unseen. Everything under the hood is dry.

Camry 2012+ :: Strong Smell Coming From Vents After 1K Miles Or Less On Vehicle

I have done some reading of past threads regarding both Gen 7 Camry with people having an issue with a strong smell coming from their vents after perhaps 1K miles or less on their vehicle. Looks like some people had it fixed (some fixing it by themselves) while others continued to experience the problem. Similar thread regarding Toyota Camry Hybrid but only brief thread. Then another thread regarding perhaps another smell like from plastics /battery (?) in Prius while I was on the Prius threads.

Has this problem been addressed/resolved either by Toyota or by owners who simply fixed it themselves? I also do not know if the Prius offensive odor (someone who was testing them noticed it while test driving) is a totally different thing (like I say someone said it was from plastics or battery itself, not sure.... )

These are things I never even thought of /considered when looking for a new vehicle, and never experienced in my older Camry.

Phaeton :: Exhaust Smoke Smell In Cabin

From time to time, i get some exhaust smoke smell in the car, when driving slow or standing in a queue.

90% of the time everything it's perfect, but at a sudden moment, the rpm is rising with 50 or so, the instant consumption rises from let's say 1.4l/h to 1.8-2.0l/h when in gear and standing, i get a small vibration and then the exhaust smell appears.

If i'm closing the recirculation, then no more smell.

After 15-20 min, everything get back as it use to be, 1.4l/h consumption, no vibrations no smells no nothing.

This i think happens when the dpf is cleaning and i cought with vcds of a friend when it happened and the exhaust temp was 350 celsius or something. Usually is 200 degrees celsius, so it is a dpf regeneration. Also the car is running smoother after this.

Still..the smoke smell... it's annoying and quite strong. There is no sign of smoke from the exhaust pipes, flexible pipe or whatever. There is no sign at all anywhere.

I have a small theory but i don't know from where to start. Usually the catalyst temp is 200 degrees. When it's 350, it expanding more, or at least the cracks are expanding and smoke+smell is from there...but there is no sign anywhere.
