As car idle exhaust smell funny not normal as my other cars what can cause this

SOURCE: heavy exhaust smell when idling or warming up the

most likely an o2 sensor is bad...but if it were bad, it should throw the check engine light before long, if it already hasnt. the oxygen sensor is what makes the air/fuel ratio mixture, thus if its bad depending on which one, either the vehicle will run way tooo lean, or way to rich therefore smelling raw fuel when running at idle. hope this helps

A dustry road would not affect the fuel filter. You need to supply more exact details of what it takes to get it started.

SOURCE: smell exhaust inside car

I had issue similar and the end of tailpipe was missing and causing the fumes to come up inside the rear bumper and circulate into the car.

SOURCE: strong gas smell inside of car

is there a leak in your fuel line, or possibly your fuel filter, if you see raw gas leaking, then it is dangerous for you tio continue to drive it, it only takes one spark to ignite it, however, if the smell is just your car burning rich and the exhaust has holes in it, it will smell up the inside of your car. And yes if your carb. is burning too rich then it needs adjusted. Wasting your fuel, and overloading your engine. I hope some of this was helpfull.

SOURCE: When I start my car or it idles I smell gas. What could cause this?

If the engine is running rich, you should have a check engine light on.
If you do, have the computer scanned for trouble codes.
It could be a fuel leak in the line or around the injectors too.
