I am getting an intermittent SES light. This generally happens first thing in the morning. It will start flashing just for a few seconds after driving a mile or so and then intermittent for the next few miles(5or6 approximately ). After that I can drive all day long without an issue. The motors sounds fine, not missing or loss of power. I am getting codes p1316 and p1211. This has been going on for a few months, maybe getting a little worse with the colder weather and it shows up more with pulling a load with the truck. Truck is a '99 F350 FPS with superchip set on tow.
