This morning I started my truck and it idled very rough and sounded as loud as a Powerstroke. The service engine light soon came on and I turned it off after running 2 or 3 minutes. I waited about 10 minutes then started it again to move it back into the garage as I was afraid it would damage the engine to drive it this way. It ran fine with the service engine light still on, so I drove it to town and warmed it up. (outside temp 35f). It ran fine and the check engine light went off. I tried to drain any water from the fuel filter and nothing, not even fuel came out. I changed the filter about 10k ago. Edited by: Walter
