I noticed recently that I smell gas from my exhaust. Not when it first starts up... but even after I stop from a full drive. Around the same time I noticed my car backfires a little more often as well. Gas mileage seems the same. I am due for spark plugs in 3,000 more miles just fyi.

Am I not burning all of my fuel for some reason? Or is it all in my head? Thanks
