Hi, I need to replace 8 GDI injectors on a 2016, Sierra 1500, 5.3 NON flex fuel. The dealer said injectors 1,3 and 8 were bad, but best to replace all of them. That I agree with.
GM says I have 3 different injectors installed, low flow, normal flow, and high flow.
I read on GM tech-link, that if the injector order were mixed up, the “normal flow” injector could be installed for all 8 injectors, but you could have fuel trim and emission problems.
With 4 injectors per bank, what injector do I need two of?
In what position does each injector go?
Are each injector banks the same?
Thanks for any help
