i guess leaky fuel injectors. esp u posting this in nov when its cold or colder. is it worse when its cold? mine was. i had a turbo lebaron that was 20 yrs old but only ~75k miles that had this problem. i'd step out of it smelling strongly of gas, not fun. i sold that car to my friend and after about a half year it got worse and worse mileage, eventually stranding him, he never fixed the injectors. sometimes ppl clean the injectors by hand, those liquid cleaners prob won't do much at this point.
maybe gas cap related?
