What causes an engine to run rough no check engine lamp on and a strong fuel smell coming out of exhaust in 1994 Chevy caprice with a 265 CID engine?

Try replacing your Oxygen sensors they are located on the catalytic converter. I had the same problem with my 94 Caprice and that turned out to be the problem.

Why might we have an oily smell coming from our vents in the car especially at stoplights?

I think that you may have an oil leak,which is getting on to the front section of the exhaust and whilst travelling along the fumes are being blown away, unlike standing at trafic lights, they are rising up under the bonnet and drifting through the heater/air vents, especially after along motorway run ,I have also had this happen to me!!

What does it mean to smell something burning but nothing is burning?

I think that we drink to much alcohol and our brains can handle drinking to much.

How does a clean diesel engine work?

Clean diesel. No, it's not an oxymoron anymore--it's a term that'll be bandied around frequently as more diesels are introduced. So what exactly is a clean diesel engine?

Clean diesel is a combo: take a diesel engine with advanced CRD fuel delivery and add a diesel particulate filter and selective catalytic reduction exhaust scrubbing technology that takes advantage of the 15 ppm sulfur content of ultra low sulfur diesel (ULSD). Package it all up for a clean diesel that is aimed at meeting increasingly strict diesel emissions legislation.

The pluses: not only do clean diesels offer sparkling emissions, particulate matter (soot) is reduced 95 percent or more (over standard diesels), and there's also a substantial reduction in oxides of nitrogen (NOx) and sulfur. Clean diesels also generate more power and have increased fuel economy since the fuel is burned more efficiently and completely (as compared to conventional diesel engines). The cons: clean diesel engines are compatible only with ULSD fuel and biodiesel/ULSD blends. While widely available, not all stations carry it. Double check that pump label--otherwise only one or two tankfuls of regular diesel fuel can seriously damage the particulate filter.

Can a gas kill you if you smell it?

there are many types of gases but if your thinking of gasoline from a gas station,it probably wouldn't hurt you if you accidentally smelled it or smelled just a bit but if you were intending to smell a lot it might hurt your breathing or make you sick but i don't know if it would kill you or not.if you are thinking of any gas,some gases might harm you greatly or even kill you but it depends on the gas

What would cause the smell of gas inside my Ford Taurus?

Why does the exhaust smell like fuel?

More than likely it is your oxygen sensor/circuit gone bad. Or Clogged, damaged, defective or faulty catalytic converter; Plugged or damaged pcv valve; Damaged or restricted exhaust system components; Restricted, loose or burned out muffler.

Clicking sound that goes away after it warms up?

Probably valve tappets/lifters/pushrods that have gummed up from dirty or overheated oil. Check the oil level and the color of the oil - when new it is gold colored, and when old it is black and sludgy.

If the engine is old and has not had oil changes at frequent intervals, there are additives available to correct the problem to some extent, ie, to get rid of the gummy sludge. Ask for advice at a reputable automotive store such as Canadian Tire, Napa or PartSource. Once the problem is corrected, be sure to change the engine oil at appropriate intervals.

Why would the exhaust of a 93 Olds Cierra 3.3 smell of raw fuel and the engine have no power after replacing the MAF sensor?

Could b an O2 sensor OR a Stuck open thermostat or one that's 2 cold-EVEN a clogged muffler or converter-many other things can cause your condition.

You were careful not to get any dirt on the hotwire/resistor in the sensor? I had a dead bug get on mine, and it didn't get burnt off like it was supposed to. This thing is very sensitive, so any debris on the wire will give you problems. You did plug in the IAT sensor, right? There is also a chance that you have the wrong MAF sensor.

If there is a strong smell of gas on the oil dip stick and your brand new Ford Five Hundred is running rough what could be wrong?

Would someone help please there is a hole in a hose that is attached to your gas tank its not leaking any gas out but there is a strong odor of gas fumes Does anyone know what that hose is called?

There are usually no more than 3 hoses coming from the tank: # The fill hose connects the fill neck to the tank # The vapor recovery line. This comes off the highest point of the tank and takes fumes to the charcoal cannister. # The fuel line. This, on a car that doesn't have an in-tank fuel pump, is not under pressure but will continue to siphon fuel from the tank if it leaks. If you are only smelling fumes and not seeing leakage, it is reasonable to guess that it is your vapor return line.

Difference between 87 octane and 91 octane?

I love this question

Octane rating indicates the ability of the fuel to resist ping or Knock inside the combustion chamber. This can be very damaging, especially on older performance cars.

Not to many years ago regular fuel was 91 octane and premium was 98

Pretty neat how they lowered the quality of the fuel and charged us more?

What you need to know:If your car calls for 87 octane regular fuel there is no benefit of running mid grade or premium.

If your car calls for 98 octane or better in the USA there are a few stations that sell it ( I know one in east Las Vegas )or you will have to visit your race fuel sales depot regularly like I do.

What do rotten oranges smell like?

Rotten oranges emit a strong, unpleasant odor that is often described as sour and pungent, reminiscent of vinegar or fermentation. The breakdown of sugars and organic compounds in the fruit leads to the release of volatile compounds, which contribute to the foul smell. Additionally, mold growth can produce musty and earthy scents, further intensifying the overall stench of decay.

What does it mean when black smoke comes out the exhaust and the car starts going about 30 MPH?

sounds like it could be your oxygen sensor. If it was me I'd replace it. If you smell a strong odor of gas, it could be your MAP sensor. You might also have a bad pickup in the distributor. Good luck.

Why do engines on cars sometimes give off a sulfur like rotten egg smell?

Answer

Because your motor is running too rich and the unburnt fuel is being burned in the catalytic converter, it makes the sulfur smell. At least this is what I've been told.
