Rough idle and no pedal response?

Those are the symptoms I am having with the truck. It started on Friday, I was driving home from work and the pedal was very weak. I had to give it a lot of pedal to get it to go anywhere. Then the truck started rough idling and stalling out when it went to an idle, it would run perfectly fine as long as you were moving. When I caught a red light it would die, so I unplugged the ICP and it started idling smothe again.

I bought an icp from Ford installed it and the same thing was happening. I drove it around for a few and nothing changed.

I bought an Adrenaline HPOP and installed that, got it running and for about 1 min it idled good then went to crap. Running rough again, and no pedal. We decided to try one more part and put in a cam position sensor and that didn't change anything either.

I am at a loss at the moment, it will run like a scalded dog when I am moving but when I have to stop it runs like crap. What does everyone suggest I do next?

Thanks
Vic

I forgot to post that I have a new set of Full Force stage 1 sticks with 1800 miles on them. I am currently running on cf'ed and filtered w85 with new filters.

Nope, I bought the sticks from Dp-Tuner with the f6 chip so the tunes are for the injectors. I have not had them make me new tunes for the Adrenaline yet but I figured it was running fine with the old HPOP so I figured the new pump would at least clean up the idle.

I have a check engine light on now and when it was running on Friday before I unplugged the ICP I didn't have a constant CEL.

Are you getting alot of smoke?? Have you tried running a tank of just D2 & burning the crap out of her?? The 50 cent mod is a good idea regardless. I presently have a 25 cent mod. Couldn't afford to do the passenger side.

Canadian of course. If I had a US one that would be no problem cause they are not worth as much.

I drive the truck this am and had my friends shop scan it and he came back with a p1280 code. It is an ICP code for low pressure. I can't clear it out, it keeps coming back. I cleaned the ICP with brake clean and the connector. What are the chances of a new from the dealer ICP being bad?
