I have an 2003 6.0 im having an injector problem I believe. but reading on some of these post people are getting alot of white smoke... My truck has no problem starting in the morning it fires right up sounds good the only thing i noticed is that at idle it shakes a little bit as if the motor mounts are bad. the trucks isnt an everyday driver i drive it maybe once a week if that, My dad came to my house and barrowed it he lives about 75 miles away from me. He called me this morning while he was driving it saying it was spulling black smoke everywhere.. he took it to a mechanic and the mechanic said its #3 injector. I just replaced the #3 injector about 4 months ago while i was on deployment and also replaced the FICM the same time. about a month ago i pulled my EGR valve out and cleaned it up... does anyone what it could b? your guys inputs would be greatly appreciated thanks so much..
