confused F250 Missing

I have a 2001 F250 V10 with 123000 miles on it. When you first crank it, it runs fine for a few min. It then drops the RPMs and sounds like it is not getting enough fuel. It will do this for a few min. it then sounds like it gets fuel but sputters. Just the other day while driving it down the road the truck began to surge. It would go from 2000 rpms to 3000 rpms. The check engine light is not on. I have replaced the spark plugs, replace all 10 COPs, fuel filter, checked CAT and I am still having an issue. Please help, I do not know where to go from here.

Re: F250 Missing

Unfortunately it is going to be very difficult to diagnose without a scan tool. It really still sounds like a misfire. Could have pending codes with no light or just not frequent enough to turn on the light.

Re: F250 Missing

Is it possible that it could be a weak fuel pump? When it runs it runs fine.

Re: F250 Missing

No leaks from vacuum hoses or PCV valve or hoses ?

Re: F250 Missing

I had a mechanic spray carb cleaner around the hoses and it did not appear to have any leaks. It is not throwing any codes either. It seams like once it warms up good it stops. I just do not understand what else it would be or how to find out. Is this a symptom of the fuel pressure regulator?

Re: F250 Missing

Not usually a symptom of a fuel pressure regulator. A scan tool that has power balance/ misfire data info will help a ton.
