UPDATE:
Night #1...got in the truck last night to drive it for the first time in 24 hours, problem gone? Started perfectly, idled down to 750 rpm after a few minutes, shifted and drove perfectly. Odd but somewhat glad...here is why. Something hit me earlier and I hadn’t made this connection until tonight. I had Krown applied to the truck a couple days ago. It is a rust proofing spray. They do the underside, inside door panels, parts of the engine bay. PERHAPS some of the product got on to something it shouldn’t have like a sensor, inside the O2 sensor, etc...? All seemed back to normal last night. Thoughts? I will continue updating every night until Christmas to see if the problem returns. Another thing to mention, it was about 15 degrees cooler outside last night compared to the night before, not sure if that would cause the engine to run “normally” again.
