hey everybody. have a 2006 6.0 with no mods. just a work truck. have a rough idle then dies when hot. won't restart till cooled down. high pressure oil leak right? Have ae with ford bundle. have good ficm voltage. icp desired and actual are within 15psi. Did the icp air test but fried my ipr valve in the process. Got a new ipr valve but didn't want to fry the new one. got a ipr test fitting to air test directly from the ipr port. problem is now i don't hear any air leaks from either valve cover or the high pressure oil pump. Im at a loss. updated the stc fitting anyway since i was in there. dummy plugs and stand pipes are updated as well. Have over 200,000 on her and she still feels very strong. any help would be greatly appreciated.
