"Hunting for fuel?"

[SMOKIN01CUMMINS]

I need some help on my 05. When I go to stop and apply the brake the engine will "hunt" for fuel. It is only when I roll for a bit an apply brakes and my tack goes from the 900 rpms idle and drops to 500 rpms and will go back and fourth? Any ideas?

Try it with the Edge disconnected.

FCA possibly and as posted put back to stock

I have the edge off of it now and its the same thing regardless. I guess you can say it "surges" instead of hunts. And after complete stop it goes back to normal idle.

sticky injector?

No real signs of injectors that stick out. How could one test the fca?

Put some 2 stroke oil in the fuel tank this will lube the sticky FCA

Put some 2 stroke oil in the fuel tank this will lube the sticky FCA

that will usually diagnose an FCA acting erratic.
Do you feel /hear it surging or or you simply watching the tach?
Any CELS?
