:confused: I have a 1994 3500 HD Chevy, 6.5 turbo. Problem is real loud rattle and knocks till temp is up to around 200. After that it sounds quiet and normal. I feel it's a sensor of some type but have no clue where to start. It's not a mechanical knock, sounds like fuel to me. I am inclined to think it's electrical and any draw at all electrically messes with the guages. Also if the lights are on, or my foot is on the brake it won't shut off. Take your foot off the brake or shut the lights off and it shuts right off. HELP... this is driving me crazy..Engine itself runs fine. no skips or smoke at all. Thanks.
