Have you changed fuel filters recently? Perhaps they're due?

My 05 was doing the same thing but I would sometimes have a dead go pedal. I know it sounds dumb, but I unpluged the harness going to the go pedal and plugged it back in and I haven't had the problem in 2 weeks. I have adj. pedals and maybe it got loose some how.

Have the same problem with my 04psd. Change fuel filters, drained the water separator, cleaned the egr no changes. I tried disconnecting the electrical plug above the gas pedal and reconnected. Hopefully this will take care of it. Didn't get a chance to test it this evening, I will tomorrow.

Truck still doing the same thing. Does anyone have any idea if the TPS, throttle position sensor, is covered by the extended warranty. How much are they?

I have a similar problem, maybe the same thing. My truck is an o6', only mod is an after cat exhaust. The truck will sometimes idle rough, as if it were not getting fuel or something. It fluctuates in idle a couple hundred rpm's or so ie: updownupdown etc. If I rev it up a couple times, it clears away and idles properly. The truck is new, I've only logged 12,000 miles on it. Ford say'sif there's no check engine light, there's nothing they can do unless it happens while Im at the dealership.

My 04 did the same thing. At first I was changing my fuel filters every 15K and the problem eventualy got so bad that it would die at a red light. Problem solved when I started changing every 7.5k along with oil. I also quit using cheap filters to. Im now using wix and have been trouble free for 30K.

Mine started missing really bad, would die and not start back until the engine was cold again. It was my HPOP, I hope it something cheaper and more simple than the HPOP for you. Mine wasn't throwing codes either.

First of all is the miss only on a cold start? The newest ford reflash will cure that...

The miss could be a lot of things, injectors and the ICP sensor or connector are the most common....other causes could be the APP sensor, chafed wiring harnesses, and a host of other things...

check for codes first.....
