Thank you @mmj!
I replace the PCV oil trap, air filter, oil filter, and completed an oil change a few days before my post. Nothing changed!
Last night, I cleaned the throttle body and replaced the gasket. I cleared the code but it returned within a mile distance.

isn't the video about cleaning the MAF?


By MountainManJoe 08/02/2022 10:16 pm
 

I cleaned the MAF sensor as well but the car wouldn’t allow me to clear the code. But it allowed me to clear the code after I cleaned the throttle body.
I also searched for a vacuum leak.

Whats the fuel trim readings?
Since its happening to all cylinders might look at vac leak

These data show that you might not have vacuum leak. The injectors might be dirty. Try some fuel injector cleaner.

A few days after your response. The Check Engine light turned off after I put gas in the car 🤷🏾‍♂️. The light hasn’t illuminated since but I will purchase ATS Chemical 505CRF fuel treatment. As soon as it is available!

correction:

Bank 1  LTFT should be near 0 
Im still thinking vac leak

The Check Engine light has been off for three weeks now. I preordered ATS Chemical 505CRF and 505CRO.
I didn’t find a leak. But I will purchase the tools from Scotty Kilmer’s Amazon list to see if I missed a possible leak.
