Stalling problem after oil change?

[teberhard]

Just changed my oil as I always do with rotella T and motorcraft filter. Oil level is perfect. The truck will start up but as soon as you hit the throttle it will stall at anything over 1300 rpm. Checked the air filter and its fine. Replaced the fuel filter to make sure that isn't a problem. Check codes with scan tool and nothing out of ordinary. I always have a 0541. Check icp pressure and duty cycle and they seem low to me. At idle 480 pressure and 10% duty cycle. I can rev the engine for an instant before it stalls and icp pressure is 1688 and duty cycle 18%.

Any ideas?

480 psi and 10% isn't low for idle. Have you monitored the oil pressure with an external gauge? I check mine at the HPOP reservoir as it is what feeds the HPOP so if it is low there, you have issues.

Try unplugging the ICP sensor and see if it changes anything.

You did nothing else, other than changed the oil right?

Yup, just an oil change. Unplugging icp doesn't change anything. I actually changed the icp last year.

Bad LPOP not providing enough oil to the HPOP?
