The problem is called dead pedal. When you step on the gas pedal you get no response at all until you let off then the truck lunges forward usually leaving halfway in a intersection. Happened on 6-26-03 again, leaving me in intersection with semi approaching and vehicle pulled up behind me, fortunately the semi had room to stop. Dealer has tried to fix this but has no idea whats causing this. After looking into this on fordtrucks.com/forums I found I'm not the only one with this problem.

Consumer stated vehicle cut off 3-4 times while driving on the highway. Each time he took vehicle to the dealer/mechanic they replaced a part or did some adjustments, and claimed it was repaired, but the problem recurred.
My 6.0l ford diesel will not accelerate properly and is a danger to my and my family. By far I am not alone and you can get more information by logging on to thedieselstop.com and look in the 6.0l forum.
My 2003 f-350 super duty 5.4, with 3,500 miles has an engine knock on cold start-up.the dealer had the truck for a week, and said this is normal.I took an oil sample, and had it tested, and was told the sample had to come from a high mileage motor,the sample shows traces of bearing material.the dealer says this is normal for "break-in" oil.I think there is more wrong, and don't want to ruin it.this is a $30,000 truck, and I can't see tearing it up.
Dangerious when pulling out in traffic! Flat spot in launch!
The engine stalled while driving and it took off really fast from a complete stop. The vehicle was taken to the dealer on 8/5/2003. The dealer did not identify the problem to the consumer. When picking up the vehicle from the dealer the vehicle still had the same problem. The dealer told the consumer to drive it for a couple of days and bring it back if it doesn't get better. Please provide details.
The vehicle started to shut off while driving down the road. The vehicle was taken to the dealer on four occasions, and each time they said the problem was fixed. The vehicle was still at the dealer and not running. *mr *ts

2003 ford f-350 6.0 liter engine diesel runaway after owning 13 days. Vehicle has been out of service and at dealers for over three weeks.
Consumer states intermittently loose the brake. No power steering. Dealer notified. Please provide further information.
Vehicle lost power (and never returned) while passing another vehicle on the highway. Check engine light came on after 20 miles of driving under the lost power condition. Took the truck to the dealer and they replaced the egr valve. This happened at only 3500 miles. I wish ford would test their vehicles instead of having the consumer test them for them on the highways.
I had a brand new 6.0 powerstroke supercharger blow up on me and it only had 244 miles on it. So the dealership gave me a new truck. Then the new truck had the same problem at 8,000 miles and it was the supercharger to but it also burnt an injector out and told me I needed a new engine and ford was not going to cover it under warranty because it had an after market part on it, even though I had the same problem in the first truck ,but first truck did not have the aftermarket part on it . So I should not be liable for it.
Ford f350 crew cab with 6.0-liter diesel engine. The turbo randomly shuts down and the vehicle will not accelerate over 45 - 50 MPH. The only temporary fix is to turn the engine off and restart the vehicle. My spouse was nearly rear ended by a hay truck while trying to get onto the highway. The vehicle has had three computer program updates - none of which has fixed the problem. Ford has now told the fleet service department they are aware of the problem but do not know how to fix it. Ford does not have an "update" to fix this problem and told the service department to return the vehicle to us to drive until they come up with a solution.
