The fuel to air mixture is too rich. To fully answer your question I would need to know what kind of car, make, model, year. Is it fuel injected or carburator? Is it cold out or warm where you live? depends on what type u have . if it's a carb like the other guy said it might b running rich or the choke might not b shutting off right if it's fuel injected then the oxygen sensor is to blame
nuthing
yes nd it will also give of a oily smell with it
I would start by checking any leaks in your exhaust and fuel filter area, if there is any leaks throughout the exhaust the smell of gasoline or exhaust may come through into the interior.
most likely you have a leak in the exhaust pipes or a bad catalytic converter
The burning smell from the exhaust pipe may be caused from oil or transmission fluid leaking into the exhaust pipe. For example, if your turbo is failing on the car, then that can cause leakage from the manifold into the exhaust pipe. There may be other reasons, too, which other people will be better articulating.
Any exhaust smell in a car cab indicates an exhaust leak somewhere along the line. Th reason you don't smell it while driving is because the air flowing air under the car is blowing the exhaust gasses away before it can rise into the cab. After the car sits for a while, the gasses seep out of the leak, and up into the cab.
Its just the wax they have on them to stop them from rusting while in storage
sounds like you use a bad mechanic a good mechanic would replace a cracked exhaust manifold to start with if you can smell gas,there is obvioulsy a leak in the fuel system. this needs to be found as it is a fire hazard
your catayltic converter is bad and needs to replaced
exhaust leak or a possible fuel line leak
in the exhaust possibly but in the cabin more often means leaking heater core.
Smell the oil, if smells like some gas is in it. then it would be ur fuel pressure regulator.
