The CEL did not initially illuminate. This occured in the middle of nowhere Texas and I had to drive it about 200 miles in this condition. THe CEL did come on until the next day when I drove it to the dealer. Unburned fuel can be smelled from the exhaust at “idle” and the CEL could now be the result of fouling of the O2 sensor. I am at a loss as I don’t believe my local Ford dealer service center is credible and the next dealer is about 50 miles away.
