Ok 04 Lb7 mods in sig. Few days ago started it up and after about 10 min of idle in started sounding like a powerjoke.
Got P0088-89-90 codes and 1940 rpm limiter.
I always run diesel kleen and fuel filter is 3k miles old.
Well I logged it with Efi.
Desired rail psi is normal but actual is 25-26k no matter what.
I figured a stuck open fpr so I ordered a LBZ fpr to put in it.
My quetion is could driving with high rail pressure take out injectors? I had to drive it home and #4 injector is out of spec but I was just hoping it was due to 26k of rail pessure.
No fuel in oil and no smoke.
Thx guys.
