Ford f250 2003 super duty diesel 6L - loss of power and idle fluctuates

Loss of power and idle fluctuates at idle when warming up and when warm. Notice power loss when acelerating. Idle fluctuates from up and down like an electical load is put on the moter. Idle will stay low for about 10 seconds (like there is a load on the moter) then go back up (like the load has been lifted) for 30 sec or so.. these time interval are inconsistent.
Any ideas?

    I have a 2003 F250 Diesel SuperCrew Pickup. It has begun to loose power and fluctuate in idle. It has lost power while in a pull as well as just increased elevation. I was sitting at idle for about 5 min. today and it just shut down. This is a new addition to these frequent problems. I can drive 50 miles or so with no evident problem and then just experience a power loss at any given time or strain.

    Thanks for reviewing

    I also have an 03 250 SD diesel. Truck started revving or surging during idle and while driving. Now it is surging then goes to missing or bogging down. Had it at the mechanics. changed fuel filters, ran a solvent through the diesel. clean oil change. everyone is stumped. any suggestions?

Icp sensor, definitly. you can get to it but you have to go from the bottom. remove the trans filler tube, and lower the the trans slightly, then you can remove the turbo heat shield and get to the sensor, you will need a 1 1/16" 12 point crows foot socket for the sensor its self.

ICP Sensor... The Injection Control Pressure Sensor... part is about $100... very hard to find and get to... located on the back side of motor under the Turbo almost impossible to get to... I work on my stuff all the time and I took it in to be fixed by FORD about $350 I think I spent total. My code reader was flashing code #P2285 ICP Sensor... Hope this fixes yours, it did mine.

nothing.... it's a diesel. transmission compensates shift point for higher rpm to assist in warm up. start it up and have a coffee. than drive..

2000 ford super duty 7.3 diesel will not cold start

you need to have the engine coolant switch checked,since the computer relies solely on sensors,the ect tells the computer how cold or hot it is so the computer will make it a rich or lean mixture to start the engine,if it tells the computer that it is 75 degrees the computer will lean the mixture like starting a car in the winter without a choke.

2006 f350 wont start if warm

It is Vapor Locking at the Pump. The O rings are Swelling too much and will not allow the fuel to leave the Pump or enter the Injectors.
Ford knows of this Problem. Call a Local Mechanic He will have to Fix the Problem
