Which by cylinder number are the 4 injectors that are shut down in V4 mode?

What is your question?

I have already replaced two injectors in my 2016 Cadillac Escalade recently at 70K miles over the span of 7 months. They were replaced in cylinder numbers 2 and 8. I suspect that the number 4 and 6 injectors will be the next to be replaced as I believe the four injectors that are shut down in V4 mode are 2,4,6,8. Is my assumption correct or is it 1,3,5,7 injectors or is it a different sequence?

What makes this problem better or worse?

Probably the age and 70K miles is the problem.

How long has your 2016 Cadillac Escalade had this problem?

Over a period of 7 months two injectors replaced
