Hello. I have a 2004 f350 with the ICP sensor on the passenger valve cover. 200k miles, bullet proof EGR cooler (however welded shut at Y), banks ram elbow and cooler, bd up-pipes and manifolds, Edge tuner, stage 2 turbo. Almost everything has been replaced on this thing.
Problem I have is when it is cold. It will not climb a hill in forward or reverse. If I'm in that situation, I can floor it and you can hardly tell. Won't build boost or RPMs. After it idles for 5-10 minutes it will start building boost but rather slow. Typically 3-5 seconds before things start engaging then it wants to run. I have to let off the throttle or if will spin the tires. I've done a boost leak check. The only place I have air leaking is under the EGR valve. I think it is possibly coming out of the small hole off to the side. I've tried removing the EGR valve and plating it off. It seals everything off completely but still did not solve my issue. I've tried replacing the EGR valve with a new one and experienced the same leak. The only code that comes up periodically is P0404. It revs up fine in park, but will not react once in gear.
Thanks for your time!
