Disconnect the battery, turn on the light switch. Come back in 15 minutes. Turn the light switch off.
Hook the battery back up.
Start the car and let it idle for 30 seconds.
Apply all the electical and mechanical loads the engine will see: lights, AC, crank steering wheel stop to stop all within the next 30 seconds.
Let the car idle for 5 minutes.
Go for a 20 minute ride, putting the car through the paces it will see during normal use.
It's reprogrammed.
Next time the CEL comes on, go to AutoZone and ask one of their drones to read the codes. Write them down. Come back here and post them and ask for advise.
MAS sensors are easy to clean. Brake parts spray cleaner works very well.
Your injectors are probably fine.
The fuel filter "might" have trapped some junk from a fillup. Replacing it will remove it as a likely source for awhile. Unfortunately, one bad tank of gas can happen anytime.
