Intermittent loss of power (could be describe momentarily stuttering) with momentary illumination of the check engine soon light. Its only happened a couple of times. Maybe about a year ago (I changed the fuel filter after it occurred). It occurred again about a month ago and then again yesterday. About a month ago I had a friend with a scanner look at the codes and he said there was only one and it was for low fuel pressure. Its been maybe 5k since I changed the fuel filter.

The truck is driven intermittently, maybe 5k or 6k a year, and usually parked with a full tank of fuel.

Any suggestions on areas I should look at to correct this?

I got my stock 2001 F350 4x4 manual transmission in 2004 with about 157k miles. Today I've got about 228k miles.

 

Get a 100 psi tire Guage and test the pressure. Should be at least 50.

Change fuel filter again. If pressure is low. If in a South area you could get algea that will show on filter like slime.

 

Do you know the code number that was thrown? Reason I ask, is there is not a code which indicated low fuel pressure. The PCM does not monitor fuel pressure, so it really doesn't know if it is low. There is, however, a code for low high pressure oil, which is pretty common to see.

 

It was probably the dreaded p1211.

 

Yes, this is the code I was referring to in my post above.

 

So I took the truck to the dealer, the mechanic said that the injector pressure control solenoid (F6TZ*9F838*A) was bad and that the thermostat was stuck open. He replaced both and the truck seems to be running like a champ.

 

Thanks for checking back in with the results!

Bad ICP was not the first thing I would have guessed, but I'm glad it's running like a champ again.
