cel flashing, gasoline smell white smoke from tail pipe

While towing a travel trailer in Phoenix on I-10 east bound at 75mph the FLEX suddenly lost power, check engine light came on flashing. Since this was not the first time this happened I had an idea where the problem was, hooking up my scan tool while limping the vehicle to a safe location showed consistent misfire on cylinder 1. Codes presented by scan tool were P0301 and P00c6, first code is specific to this issue showing misfire condition, second code is more general meaning there is a problem with the drive train. Swapped coils between cylinder 6 and 1 but the problem persisted. Ford Roadside assistance would only cover a tow of the car, not the trailer attached to the car so once traffic lightened up the vehicle and trailer were limped to my home and a tow was setup for just the FLEX to the closest dealer. Roadside assistance took two and a half hours to get the tow truck to pickup my vehicle, I'm glad I was at home this time. Once picked up the car did not arrive at the dealership for another 2 hours, it is a 20 minute drive. The service advisor called about three hours after the keys were handed off to see why the car was towed in. The voicemail left at the dealership after hours apparently is not a good way to communicate issues, nor is Ford roadside assistance as they were given all the details of codes and that I swapped coils to see if that was the problem, none of this information was passed on to the service department at the dealership. What gets me hot is that I left a note with codes and what I did in the car as well, the tow truck driver saw this note but didn't pass it on. Additionally had the service advisor tried to start the car they would have seen, heard, and felt the issue, but instead they sat on it for close to the whole day. Once I relayed the fact that I didn't have it towed in for fun times Ford took another 6 hours to even scan the codes and using their own tool got the same codes and made the same diagnosis that I had done on the side of the road, bad injector on cylinder 1. Service then quoted me a price for replacing just the one injector and another quote for replacing all 6 since we were already in there all of them should be done. This story changed once they went back out to the car and noticed that the milage is only 35600, just shy of the point where the extended warranty kicks in. Once the service advisor saw this he changed his story to just the one injector will be replaced, it was no longer a good idea to replace all the injectors. Still it took another full day for the car to be repaired. Still something is wrong, there is a strange hesitation when in 4th gear around 5200rpm the car looses power for less than a second and then surges back, like the blowout valves are being triggered which leads me to deliver there is a small boost leak some where. This was the first American car I purchased in 20 years, and I doubt there will be anymore Fords going into my garage.
