Hi, the check engine light on my 2001 F350 7.3L diesel comes on pretty consistently upon deceleration, and then goes off upon accelaration and stays off when running at steady rpms. There is no visible effect on performance or operation. I haven't check the codes yet, but was wondering if anyone has experienced this and has ideas on what the issue might be. Thanks.
