P1128 Code

Howdy folks.

I have been getting a recurring P1128 CEL code of late. I had it happen a while ago then it went away but now I am getting it every time I drive the car. No other codes such as P1130 have appeared. I have been just clearing them with my Autel.

I tried cleaning the MAF to no avail. Am I looking at a replacement MAF or vacuum leak or O2 sensor?

Any suggestions would be appreciated.
