Fuel rail pressure sensor?
 

will the fuel rail pressure sensor going bad make the truck lope, and run like it has a fuel issue.

a bad fca could possibly do that, have you unhooked the EZ and tried it stock?

Yes, That was the first thing I did.

have a buddy with a 05-07 truck you could borrow the fca off of since it only takes a few min to change?

I live in Alaska.

what is your lift pump pressure? Lope? Is the idle going up and down?
What is your fuel rail pressure at idle? Should be round 9,000 lbs.

my idle is going up and down what is this?

i'm leaning toward the FCA with the idle going up and down new one from cummins is about $150

By lope I mean my truck sounds like it has a cam in it. How would I check lift pump pressure or fuel rail pressure.

lift pump press can be checked with a mechanical guage but the rail pressure will have to be checked with a scan tool
