My 1993 civic has 171,000 miles and still runs really well...but the fume smell is killer. Stale gas or something??? The worst is when the car is idling at a full stop. I get a similar smell when i take the filler cap off...any ideas??? Thanks in advance.

 

Same here but my motor is pretty well built, so I think its just running a bitch rich... maybe its your injectors having some problems or something.
