I
think the most important thing that I changed was the injector staging.
Yes; because it was
trying to run at idle with all four injectors instead of just two.
I
had previously discounted this as the problem because when I tried running on
either set of injectors alone the surging still occured. I must have had
some other problem as well.
This is because when
you turn off one set of injectors, it doubles the flow to the others.
