Ford F250 Super Duty: 99 7.3L powerstroke starts easily but…

Customer Question
99 7.3L powerstroke starts easily...
99 7.3L powerstroke starts easily but when accelerating the engines stalls. After engine sits for a while it will restart. If you let it warm up 5 to 10 min after first starting it runs just fine. Problem comes back it engine sits for 4 or 5 hours. Changed cam position sensor and injection pressure control sensor with no help. Any ideas what could be causing this.

Hello and thanks for choosing just answer. When you went to change the icp sensor was there oil in the old sensor? How long after the vehicle is driven does it stall?
Ask Your Own Ford Question
Customer reply replied 3 years ago

as soon as you try to accerate quickly

Customer reply replied 3 years ago

it stalls as soon as you try to accerate and reach around 1500 to 2000 rmp

Ford Mechanic: James, Ford Technician replied 3 years ago
Did the the old icp sensor have oil in it? Do you have a chip or programmer installed?

It did have some oil, and does not have a chip.

It sounds like the throttle pedal is likely bad if it's quiting when you step on it. Do you have a way to test for codes?
Ask Your Own Ford Question
Customer reply replied 3 years ago

I am not having a problem starting the engine. I am only having an issue when it is not warmed up. Both batteries are relatively new and i am not sure why you say there could be an issue with the starter when it starts easily.

Ford Mechanic: James, Ford Technician replied 3 years ago
I'm sorry I edited that because it was meant for someone else. It shouldn't still be up there. If it is I'm sorry. The last thing I posted was I believe your throttle pedal may very well be the issue. Do you have a way to test for codes?

Customer reply replied 3 years ago

I can check the throttle, I have checked codes and there none that come up.

Ford Mechanic: James, Ford Technician replied 3 years ago

vin # ***** *****
This morning when I started the truck I let warm up for 5 minutes and did not ave any issue with it stalling out. I do not see any signs of wear on the throttle. The only time this problem comes up is when I start it in the morning or after sitting several hours.
Ford Mechanic: James, Ford Technician replied 3 years ago
It stalls when you step on the pedal correct? When it will stall anyways?
Ask Your Own Ford Question
Customer reply replied 3 years ago
It only stalls under acceleration after it is first started up, once it warms for a while the problem goes away.
Ford Mechanic: James, Ford Technician replied 3 years ago
Does you scan tool monitor data like the app 1 and app2?

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey

I would (and have) recommend your site to others I was quite satisfied with the quality of the information received, the professional with whom I interacted, and the quick response time. Thanks, and be sure that I'll be back whenever I need a question answered in a hurry.
