My car smells like gas, and the odor gets stronger the longer it sets at an idle. The gas mileage has decreased by 6mpg. The first time it starts for the day the rpm's rev up an dit sounds like you ar


When you smell the strong odor of gasoline and the car runs rough the coolant temperature sensor has failed (no exceptions) The engine is usually slow to start the first time. turn it off and it starts right up next try.

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.

Own a 2001 nissan sentra check egine light is on, car will start but runs very rough and smell of fuel. It will idle roughly in park, but once in gear no power


sounds like engine rebuild time and you need to have the transmition rebuilt too. i hope this helps. if you want to try flush the engine and fuel lines with ethenol. but if you flush the engine you will need to empty the fuel tank first. after you flush the engine full with fuel and run at idol for a couple of minutes. treat the fuel. this should help the engine to run properly whilst you wait to rebuild it. give it a service too. when you flush the engine too white smoke should be emitted from the exhaust or if you have a catilitic converter the white smoke should be reduced. hope this helps.

91 Maxima Gasoline odor when I first start the car


If it is running fine, the busted bolt isn't the source of the gasoline smell. The intake manifold has vacuum, so the smell wouldn't be getting out, air would be going in, and a vacuum leak would give you poor idling. The exhaust manifold wouldn't have much raw gasoline smell. But it would have loud noise if the broken bolt were causing an exhaust leak.

Check that the vapor recovery line is not broken or disconnected. The hose connectors get cracked. If that were broken, it would cause a gasoline smell after the car has been sitting, especially if it has been sitting in the sun, heat driving gasoline vapor out of the tank. It is supposed to condense in the vapor canister, but some escapes if the line is broken. If it is broken, driving would **** out the gasoline from the line and the wind would dissipate the smell.

Or it could be a leaking injector. With the injector cover off, engine idling and cool, you can visually look for raw gas around the injectors and injector rail connections.

Hope this helps.

Strong odor of gasoline vapors


do u have a check engine light on? do u overfill the tank? which is to say when the filler nozzle clicks off do u still try to put more fuel in? in any event u most likely have a overloaded carbon canister, pull the canister out and check it for gasoline saturation, the carbon canister is located under the car in a tray near the fuel tank.

Strong gasoline smell when cold and wet weather.


the first thing to do is look under the car at the plastic canister the vaper recovery system it is in the rear some times it is coverd by a sheild the vacuume hoses are bad if you smell gas and that will turn the light on it works off a pressure senser on the tank check all the hoses

Running rough


check spark plugs, if one or more damaged this will explain rough running, and the smell of unburnt fuel, while you have plugs out give them a good clean. if they are wet with fuel then they are not sparking, wipe with soft cloth. to check if plug is sparking, take one out, leave it in the HT lead, get someone to hold it against the top of engine block and turn over engine. WARNING: HT LEADS CARRY A BIG CHARGE DO NOT HOLD LEAD WITH BARE HAND, USE SOMETHING NON CONDUCTIVE TO HOLD IT DOWN WITH ie, A BIT OF WOOD. if it sparks, its fine, put it back in, and remove another, and repeat the procedure and so on.
