Went to drop the wife off at work and the truck felt sluggish, and no boost over 10 PSI, So, I floored it and it seemed to clear itself up. Made a couple of stops on the way home and the same thing, then I noticed the CEL was on .

Of course Murphy's law comes into play as we are leaving for Reno at 5PM today. Hook my Smarty Jr up and get 3 trouble codes, P0237, P0069 and P0299. Go to clear them and the P0237 keeps coming back. Did a little research on this great DTR site and narrowed it down to my XZTS harness. Unhooked the harness, cleared the code and took her for a spin. Just like new again.

I will pull the harness completely when we get back and inspect it more closely. May be time to update and get a new harness at the same time...
