Check your Catalytic converter and muffler
For clogs
Also check your fuel filter it may be clogged

I did not see the check engine light turn on with key, but, another one did when you rekeyed the ignition.

Scan for trouble codes please.

Six year old gas in it?

It’s gonna run like absolute ass on that.

Check fuel pressure first, then…

Siphon all the old gas out, fill it up with fresh fuel, throw in some heet or dry gas for good measure

Check intake tract for rodents and nests

Try cleaning / spraying out your throttle body with some spray cleaner..... and check all your connections of air intake..... and check air filter for rodent nest as C420sailor mentioned.
