2004 nissan murano when driving i smell exaust inside the car why

You have an exhaust leak. Probably in the rear exhaust manifold. You should get this fixed right away as it could lead to Carbon Monoxide poisoning which could cause *****.

Evap emmission,control sys leak

Do not top off your gas tank. The gas is going into carbon canister which is only for fuel vapors to go into (carbon canister opening near the top of fuel neck near the gas cap). Your flooding the fuel vapor canister with liquid fuel; of course you are going to get a sensor message... 'Evap emmission,control sys leak

P0443 The fuel vapor canister reduces that gas smell on hot days outside/inside of car. The fuel vapor canister fillers bad smells from gas tank on hot days when the gas expands and burps fumes through carbon canister filter. From the canister (gas vapor fumes) goes back into the engine to be burned's a closed loop for vapors to be recycled though engine. Don't worry, once the carbon canister dries out and no longer flooded with raw fuel the code should go away...just don't let the top off fuel tank back flow into the 'Evap emission control' carbon filter near the top and close to the gas cap...:)

2004 Chevy Trailblazer V6, sounds like it is loosing pressure. Can smell exhaust inside vehicle and under hood.

A Carbon Monoxide tester for homes may be used inside your vehicle. This will verify your concerns about the fumes inside your vehicle.

If you hear something while the engine is running, you may have an exhaust leak. This is something a Muffler shop can check. I don't know about recommending a business as I probably do not live in your area.

Our site use to have affiliations with Repair shops and if you can go to an Online Expert's Repair shop you should get an honest repair.

Word of mouth advertising should get you to a good place. For an exhaust smell, since carbon monoxide is odorless, a sulfur smell would indicate problems in the Catalytic converter area. Or if your vehicle is burning a little oil, there would be a detectable odor.

Wish I could say it is an exhaust tube or O2 fitting leaking and solve your problem. Best I can say is protect yourself with a Carbon monoxide detector and have your vehicle visibly checked.

Please rate my info.

What problems are associated with EGR valves and sensors

When an EGR valve does not close properly you will get a rough idle because the EGR is suppose to be open after a set rpm to maintain exhaust flow. When an EGR has a vacuum leak in its diaphram it may not open at all and will be venting engine vacuum affecting all systems.

The sensors for the EGR work both by vacuum force and with electric magnetic coils. The backpressure of the exhaust is monitored, the emission gases are monitored, and there can be a performance cutout for full throttle passing.

These sensors are less durable than the EGR valve itself. There are false Code 401 results when the supply port for the EGR is full of carbon. The onboard diagnostics blame electric valving for not opening the flow when in fact the flow is stopped by carbon before the valving. You can have Backflow errors when there is a hole in the backflow tube, again not a sensor problem. However the EGR sensor can short out from simple condensation in the backflow tube.

You can have jerkey performance, you can hear relays clicking, and you can have unusual sulfur smells from the exhaust when the EGR is not venting properly.

You can get a free scan at Autozone or Oreillys but bear in mind that the onboard diagnostics are not flawless. I hope you have been happy with my efforts. Thank-You

L get the smell of petrol ocasionaly ,and a rattle in the exhaust?

This could potentially be serious. You probably have an exhaust leak but if you're smelling it you could be getting a large dose of carbon monoxide which can be very dangerous to your health. It accumulates over time and you're body can't get rid of it. Carbon Monoxide (CO) can kill you very fast. You need to get the exhaust system checked out and find out if there is a leak.

I have a 1995 GMC Jimmy,rough idle, carbon smell, strong gas smell coming from the left driver side, check engine light is on. Has a hard time turning on...Any suggestions?

My 94 Jimmy had similar problems, until the dirty EGR valve was replaced. We tried a million things, first. But the improvement with the new EGR valve has HUGE.

Strong smell of gas inside and outside the vehicle

there can either be a hole in the tank or in the carbon filter of the fuel system. or a bad seal on a hose leading to that Carbon filter. But assuming that the smel is stronger at the rearside, it is more likely to be an issue around the gas tank. Maybe if the belly 'sat' on a rock it could be even on the upper part of the tank(but not that likely, rather a joint again)

rate please
