Hey guys I just got an 02 7.3 powerstroke a few. Ugh ya ago he told me it needed a idm but after I went and looked and finally got the truck to crank it ran great and he really didn't no what he was talkin about much like myself. I have replaced the ipc and cps but truck still wants to suddenly die while driving and another trick it started a little whole ago is it will now idle but won't hardly let me rev it just sputters. What's rong woth my truck?! Help plz
