On this CEL Code. Comes up every few months. I reset and it shows again.
I am bone stock other that TUBI cans

 

Could be MAF? I had 1128 and 1130 codes pop up sporadically... sometimes reset, sometime would go away on their own... MAF sensor was ultimately the culprit... you might try cleaning it.

 

There you go:
P1128 Oxygen sensing adaptation, idle range, bank 1

 

Sorry for the ignorance but where is it, and how does one go about cleaning it

 

I'm the wrong person to ask but I think you need to replace it, no cleaning!

 

OK but where is it?

 

I had a loose intake hose that caused these same codes . Simply tightened the clamps and problem went away.

 

If the question is about the MAF, it is the Mass Airflow Sensor. It is located immediately after the intake. Pretty easy to remove... BUT VERY FRAGILE... You can clean it with spray on electronics cleaner.

You can also do a search on the topic for more detailed instructions.
