Hey guys, I have a 95 f350. When I start the truck the "check engine" light comes on but will idle fine. When the engine light goes off the truck will die, if I hold the gas pedal down about 2k rpm's it will stay running but will idle rough. I replaced the cam pos sensor but still does the same. If I try to drive the truck with the engine light on it will bog real bad and try to die. Any ideas? Thanks
