I had my check engine light come on this weekend. I'm was pulling a tractor (13000lbs) and stopped at the rest area to take care of business. When I got back in the truck and started it up, the check engine light came on, at idle the engine felt like it was missing or something. I shut it down for a minute and then restarted it. Light was still on but no missing feel this time. Drove the rest of the way up to the cabin. On Sat. morning went to have the code read (no engine light in the morning) and P0069 came up. I had the auto shop clear the code. What is P0069 and what causes it and is it a problem? How can you fix it?

 

I just know what it is not how to troubleshoot it.
