I have a new 08 F250 6.4 diesel with a little over 1000 miles on it. When I was stopped at a stop light it went through it's regeneration process and had hard clunk which felt like someone hit me. It actually moved the truck with my foot on the brake. This has happened a few times. I have taken it to the Ford dealer and they checked it over with nothing found wrong. Has anyone experienced this?

There have been a few members here commenting on the increased idle with the foot on the brake. I can't explain the clunk but the surging forward has been described before. I haven't read of anyone having a dealer check it out.
