Angry 2005 F-250 Hot start problem! HELP!

My Truck will start when cold. until it warms up hot it will misfire a bit (been doing for a while now) I've used hot shots secret stiction eliminator & has helped. but now it wont start hot.

Code: ICP pressure too low, Engine cranking

Had a similar problem month ago & it was a o-ring around injector blown out. but I didn't have a code like I do now.

once it fires up it will run until shut off.

Any suggestions?

I have already booked an apt with my awesome mechanic for July 4th

But if I can narrow down the problem what to try before then... ex. Sensors

Thanks to anyone who would be able to give their input!

Do an air leak test. But i would suspect the STC fitting.

You have a hpo oil leak. May be another o-ring not sure if you have a stc fitting or not with 2005 but it is the hpo causing the problem.
If you have gauges take a look at the % value of the ipr. The higher the % the more the valve is closing trying to build pressure. At idle you should see around 21% anything above 30% is no doubt a hpo leak according to Fords diagnostic values.
A ScanGaugeII is a good tool for looking at all the values.

There is a slim chance the icp has a issue when hot but again slim. You can try unplugging the icp which is on the pass valve cover and see if it will start when hot next time.
