I have a 2006 F-350 with the 6.0L motor. My check engine light came on a few days back and I had the codes checked, it was the ICP, so I changed the ICP and reset the engine light. It stayed off for about a week and came back on and again it said ICP, so this time I changed the ICP and the pigtail, and a couple days later (today) I changed the IPR, everything hooked everything back as it was before. Cleared the engine light again Now when I start my truck it kind of like lopes, and shakes at idle, and sounds like its gonna fall apart, so its not running right. I have drove it about 70 miles thinking I needed to remove some air from the hpop, with no luck, but now when I accelerate it blows black smoke, takes off like a rocket, drives better than before just wont idle right. Can someone please tell what I need to do to fix this problem? Thanks in advance.....
