2012 gas smell and drop in economy.

Getting a yummy, not good though, fuel smell when I start the 2012 5.4l Triton up. Going to replace spark plugs as a precaution and hope that does it. Also dropped in mpg from around 14 in the city to barely 11. Just hit 203,940 and didn’t see the last time plugs were changed on the carfax so guessing it’s time. Will update when I’m done with plugs. I keep seeing that spark plugs don’t do the triton thing anymore since they were updated so hopefully it goes smooth. *knocks on fake wood*

Plugs were a little dirty, worth the $125? Idk yet. First start up had no smell of fuel though…. For now….

Images 1 and 2 are one spark plug, 3 and 4 another.
