Gas fumes question.

[Gemini]

So awhile back I threw a CEL which pointed at bad o2 sensor. Drove awhile before changing the sensor and I would smell gas fumes especially after driving or at stop lights.

Recently replaced the sensor with a working used OEM one which I assumed would eliminate my bad gas mileage and fumes but my gas mileage is still the same(300 per tank , spirited city driving) and I still get the gas fumes.

We did reset the ecu as the DIY called for after installing the new/used o2 sensor and let the car idle to relearn which eliminated the CEL but bad mileage and fumes still exist.

My real question is what else could be causing the gas fumes(its very noticeable)?

Evap canister?

pop your hood and see if you smell gasoline in there. then look at the fuel injector rails where they meet the intake plenum for seepage of gasoline, or if it looks wet.

usually they leak after soo long and you will get fumes, however if u dont smell it in the engine then its somewhere else.

the evap canister only holds fuel vapors, unless your an idiot and filling up the gastank wayyyy past the limit where it shuts down. it is actually supposed to obsorb the vapors and not give it off...if it gave it off then its toast, highly unlikly..

Yea, I have to check that, Night Wold said to check to see if the a/c dump is hooked up there or some shit like that

I will check the injector seals, good idea
