Answer 2
I have this same problem, I've noticed when driving across country the car sorta changes in handling which I believe may also affect how the car Performs. But going south to north over the Grapevine mountains in California I had an issue making it up that first steep incline. First i started slowing down quickly then the engine started to die out just slow down and die out. So I was in the fast lane all the way to the left and I had to pull off to the left. The engine was bright red when I checked it but mainly the exhaust pipes coming off the pistons, But ever since that now my engine is having troubles and is misfiring cyclinder 3 and I need help diagnosing it. Its not an answer but it is similar whatever may have affected the qustioner may have happened to me -
