Smoke coming from the engine area? tail pipe?

Smoke combined with the smell of gas probably means it's running rich. In conjunction with those codes (#4 injector error and multiple misfires cyl 1 and 2), you're probably having injector issues, either leaky, incorrect spray pattern/amount, or stuck open. Have you tried running a fuel injector/fuel system cleaner through?

I never will put any type of injector cleaner or additives to my fuel/oil. I just don't feel it's needed. If I were you, I'd pull the injectors. It sounds like you have one stuck open if you have the smell of raw fuel.

Sea foam is the best cleaner in my opinion, it may help

I'm just saying he could try, it could be a gummed up injector
