Could be a number of things -
It would be nice to have the exact code number.
Have you noticed that it has trouble hot, but not cold?
You said it starts, but does it struggle to start?

Possible issues -
ICP system leak
IPR sensor or system leak
High Pressure Oil Pump or system leak
Injector o-ring leak

 

There is also an updated connector for the ICP sensor,it has 3 purple wires.

 

ill get the code today but the truck was running fine when all of the sudden it felt like it ran out of fuel but it still idled just no throttle response! ill get them after church!!

 

I have an 05, did the same thing. I was going to replace the ICP and unplugged it, looked into the connector, blew in it, plugged it back in. The motor smoothed right up! I do not know if I had a connector problem, if unplugging it while it was running (well sort of running) reset something or what. That was about 10k miles ago. It has been running great ever sense.

My ICP is in the passenger valve cover. Very easy to get at.

 

Ok my code reader said i had a p 2290 and p 0102 !!! i cant find a p 2290 most codes stop at 1999 !! does anyone know what these codes are ? Thanks

 

Hey yz 400 was that plug hard to get to i had fun changing mine i used a 1 1/16 socket after unpluging mine , the plug was full of black oil that smelled like fuel ! it was a round plug with three wires and it was behind the turbo !

 

sorry i didnt see the part where yours was easy !!! I guess they changed it on the o5 model!!!

 

I posted the code list yesterday.https://www.ford-trucks.com/forums/8...-dtc-info.html

 

P2290 Injector Control Pressure Too Low
P0102 Mass/Volume Air Flow Circuit Low Input

 

The early 04 had them under the turbo,you found your problem. Ford put it on the valve cover in 04,so yours is a early 04 witch has a late 03 motor. Replace the connector if it hasn't been done all ready,the updates are less prone to let that oil climb up the harness when the ICP sensor fails.

 

A couple of ears ago we had something similar. But it was the wiring from the throttle to the computer was chaffed at the pedal area. Ran great then nothing but idle. Glad the warranty took care of the problem.

 

Yep pain in the but but i changed out the icp sensor for 180 bucks put the plug back on and found another problem the heater core outlet hose that runs up against the fire wall was rubbing on the nut on the ecu on the valve cover so i advise everyone to make sure you arent loosing water out of that hose! Also the truck is still doing the same low idle around 200 and no throttle response!

 

Dose anyone know the p 0102 code is !
