Check your muffler and exhaust pipe for holes and also check your manifold gasket it may need replacing, exhaust fumes smell like faint fuel, if there is not leak this could be the problem.
This could be caused by a few different things....check the purge canister if the vehicle has one.....also check the fuel pressure regulator for a leaking diaphram.The air conditioning is "sucking" the fumes in from the purge canister or the pressure regulator.
Any fuel leak in the engine compartment can transfer into the cabin when the a/c is turned on. I doubt the exhaust would be confused with fuel but that's just my nose. Some vehicles have common recall problems such as the intrepid for fuel rails leaking. you should never smell fuel
Using a Diesel fuel conditioner would be good for your engine and would not be bad at all.
Fuel leak? Charcoal canister?
look for a leaky fuel line
Fuel leak at hose or fitting Carbon canister is exhausted
I would suspect you have a fuel leak at the fuel tank. Can be a fuel line leaking or the fuel pump gasket may be defective.
Smell the oil, if smells like some gas is in it. then it would be ur fuel pressure regulator.
I have the same issue with our Subaru Outback 1996. Our mechanic said we should replace the Fuel Vapor storage Canister. This is a carbon filter that stores fuel vapors that leak out of the tank. If it gets clogged with fuel on a hot day the vapor is going to leak out when you're at a stop and get pulled into the car by the AC.
I have a 1990 Buick Century 3300. Just replace the Fuel Pressure Regulator. It was leaking gas. Replace the vacum lines to the Fuel Pressure Regulator but I still smell gas inside on the driver's side compartment. The smell goes away when opening the windows. Where would there be a fuel leak that would cause the raw gas smell inside the car but not outside of the car?
Because you get dizzy from not having the fuel your body needs to function properly. Food=fuel.
I would put on new fuel filters and use some fuel conditioner.
If you smell gas from your vehicle it probably indicates a leak. Even a tiny leak will produce a fuel smell. If there is nothing obvious leaking from the fuel lines, pull the vacuum hose off the fuel pressure regulator, if there is any smell of fuel there or if gas is present, it is leaking and needs to be replaced.
City or highway...
Your fuel pump is probably really dirty and your fuel injection probably needs to be replaced. I had that same problem with my 96 Tahoe and when i would idle it would reek of fuel. I went to get all those things replaces, and not only did the smell go away, but my mpg's went up about 3 or 4 g's. take it for a tune up!
There may be a fuel leak. This may be serious. Many fires have started because of fuel leaks. Have this vehicle checked for fuel leaks.
The first thing to look for would be an exhaust leak. Check for a fuel leak on the top of the engine.
If a car begins to smell like rotten eggs and then starts acting like it has bad gas, it may have been filled with the wrong type of fuel. This smell is common when diesel fuel is burned.
exhaust leak or a possible fuel line leak
A normal cause is a fuel leak from the fuel rail. If the rail is leaking, it may be covered under a recall.
You should never smell fuel from a fuel injected vehicle. Fuel leaks can be dangerous and should be repaired as quickly as possible.
May be separate problems. A small fuel leak in the engine may be the source of the 2 scents. A coolant leak may be the source of the poor heat and burning smell. Get it checked out before you have a serious problem. Next time you run the car, shut it off, lift the hood and try to smell where the source of raw fuel is, or any rising smoke.
Possibly a leak in the fuel system somewhere.
You have a leak somewhere in the engine bay. Either carb or fuel pipe or, if injection, fuel gallery or pinhole in high pressure line.
Well, a code 43 is telling you that you have multiple misfires. The code 27 is a problem with your fuel injectors. Given this and the fact that you smell gas, I would suspect a gas leak at the fuel rail or in the line. Interrupted fuel supply would certianly cause a misfire.
you need a fuel pressure tester to do it but i would check your o-rings on your fuel injectors first they could be old and starting to crack thus the smell of gas. but first check all fuel connection mak sure they are all tight. hope this helps zorro
