If your car were running too rich or too lean, or if there were a problem with the catalytic converter you may see a diagnostic trouble code set, not all codes set a check engine light, so perhaps take it in somewhere and have the codes, if any, checked.

Either is not a normal smell, did this start happening after a fill up? Do what KenF suggested and then if nothing is found put in a bottle of Marine StaBil fuel additive this will help counteract the ethanol in the fuel, it is possible that you got more than just E10.
