2005 Chevy Impala exhaust smell

I own a 2005 Chevy Impala and this winter, I noticed a strong exhaust odor inside the vehicle and outside the vehicle. This morning, after arriving at work, I noticed smoke or exhaust coming from under the hood of the car, so I popped the hood and saw what looked like either gas or gas/oil mixture right on the top of the engine that was burning on the manifold, on the right hand side. It smelled strongly of gas. I have looked for information and I keep coming across it's either the head gasket or clogged catalytic converter. Could someone help?

    I figured out what the issue was. My fuel pressure regulator was clogged and needed to be replaced. It was actually gas I was smelling as it was smoking on the manifold.

    I had the exact same problem on my 2005 Chevy Impala. It was a strong gas smell seeping into the cabin. I replaced the fuel pressure regulator (at like 70 bucks) and the problem went away!

Neither one of these would cause gas to leak. sure it is not coolant ? if you think it is gas it is not safe to drive car as it could catch on fire. possible cause would be a leaking injector.

Burning plastic smell when cold out run heater and fan inside car and out

Are you loosing radiator fluid. sometimes the heater core will rupture and you will smell burn odor. also check for strange rubbing sounds or screeching coming from the blower fan motor. or engine exhaust manifolds are hot when car is on, make sure nothing is leaning on them which will cause a burn odor. Any odor coming from outside will find it's way inside through the fresh air vents.

Burning smell inside car. Not under hood. What could it be?

I had the same problem with my 2005 Honda Accord. I would happen only sometime but is a distant odor I smell from inside the cabin. Older Hondas sometimes have gasket problems that leak small amounts of oil onto the exhaust manifold. Ask the mechanic to go check the valve cover gaskets. They replaced a new gasket to my car at the Honda dealer and I haven't smelled that burning odor since then. Good luck.

2005 impala has wet floor but can't figure where it is coming in at

It is quite possible that the cowl vent under the hood and close to the windshield area has been allowing debris from the outside to block the evaporator case drain preventing the build up of water to drain off under the vehicle when the A/C is used. Another indication that this may be the issue is to look under the vehicle while the A/C is in use to see if it is dripping water after it has been run for approximately 20 minutes and also to see if there is a musty odor from inside the vehicle. If this is the case it is an easy fix to clear the drain tube which is located under the vehicle near the firewall. Good luck and hope this helps.

I have a 2005 chevy malibu maxx v6. car runs great, no hesitation or stalling, however a intensly strong odor of gasoline suddenly began about 3 wks ago, and is gettin stronger by the day! it Can be...

No service engine light? A loose gas cap will set a light.
You may want to inspect your fuel filler neck and anything close. For a long while its not uncommon for a person to report the fuel odor issue and have it be where some low life cut a filler neck or puntured a tank to steal fuel. But if that were the case there would usually be a service engine or gas cap light as the systems now days monitor pressures so they can detect leaks in the Evap system.

When you mention a smell though under the hood, do you think the smell could be exhaust? I have seen those manifolds crack. or maybe just a leak from a gasket or exhaust donut.

When we start the car after it has not been started and engine is cold, we get a strong exhaust odor on the inside of the car until engine has warmed up

Is the exhaust loud? If not it may not be an exhaust smell. I work at an exhaust shop and we have seen a few vehicles with the same issue. More often than not, it ends up being a fluid leak (usually oil) that has flowed on to an exhaust manifold or front pipe and on start up the fluid burns off, causing the odor. Once the fluid has burned off there is no more smell. This is no to say the leak has stopped, but the odor is less noticeable when the vehicle is moving and the fluid burns off a little at a time as opposed to all at once like it does on start up. Hope this helps to steer you in the right direction, good luck!
