Cause of gas smell....?

Question

I have a 97 Chevy Cavalier and a while ago I started to get these smells coming inside the car. It wouldn't be all of the time. Last year I had the spark plugs replaced and a month ago one shot out because it was stripped. They put something in it to rethread it and it was all better but now I have that smell of gas when I am driving. It's worse when I am driving for a while and then come to a stop and start again. What can cause a gas smell to come inside the car and what am I looking at to repair? Any kind of suggestions is appreciated. Thanks!

Answer 1

Try looking around the engine for leaks, i think it might be a fuel leak.

the smell will be just coming in through the vents.

Answer 2

If it started just after the spark plug hole repair, then take it back to the mechanic that did the work. I could be fuel is leaking at the fuel injector rail which is very close to this repair area. He may have removed a hose or an the injector rail to gain access to the spark plug. Leaking fuel is very dangerous.
