Gas mileage as fell off, not what part to start with to maybe stop this situation.

Safe to say the check engine light is on and it's not running right? (rough or weak) , hard to start? FIRST thing to check is PROPERLY scanning and watching LIVE data. NOT FREE 'Autozone' code reading!!! IF you must resort to guessing by code , then first , write down ALL DTCs present , then erase them and drive it till light (and code(s) return. Read code(s) as soon as possible after light returns. POST that code(s) and we can start with that.
o k. Thanks.
