Your exhaust may be leaking slightly at the front. The fumes can easily end up in the car this way. Exhaust gasses are poisonous so you should get it looked at as soon as you can. Another cause could be that a breather pipe has come of the engine or air box.
There may be a hole in your exhaust system causing fumes to leak into the car. This can be dangerous and should be fixed immediately.?æ

Take a second, lightly sniff gasoline fumes before its been burned, then compare with exhaust fumes, and see which you are smelling. Exhaust fumes you'll naturally smell around an idling car. unburned gasoline could be the result of an improperly set carb, mixing the wrong amounts of fuel and air, leaving you with unburned gasoline that is boiled, evaporated, and spit out the exhaust. Too much evaporated gas turns your exhaust black, so ive been told, so there could be a sign.
Could be a leak in the manifold, or a hole in the exhaust, and when you stop the car there is no pressure blowing off the fumes, so it floats up into the car.
No who, but what. All internal combustion engines emit exhaust fumes.

A smell of exhaust fumes when starting your 2004 Honda Accord could indicate a few potential issues. It may be due to a leak in the exhaust system, such as a cracked manifold or damaged gaskets, allowing fumes to escape. Alternatively, a malfunctioning catalytic converter or issues with the fuel system could be contributing to the smell. It's important to have the vehicle inspected by a professional to identify and address the problem, as exhaust fumes can be hazardous.
If the car heat has a fresh air setting, then it could be drawing air from outside of the vehicle. The fumes are most likely coming from a problem under the hood.
