OK, here's a wierd one. Took my Boss to the track this past Friday. Car ran great...had a blast...I'll post a track report in a day or two. On the way home I stopped for gas at a Shell station. Filled up with some 93 octane and went inside to get a cold drink. When I came out and started up, the car was idling very rough and almost stalling out. I decided to start driving and see what happens. No power at all...could barely get up to 60, it was missing like crazy and then check engine light started flashing. I pulled off the road, and opened the hood looking for a loose hose or wire. All looked fine. I limped back to the gas station thinking I may have gotten a tank of water (been there, done that about 15 years ago...gas station paid $700 for my repairs). Guy at the station said nobody else was having any problems with their gas. I was 110 miles from home but I know there is a Ford dealer about 15 miles away so figured I try to make it there. Started the car and it was purring like a kitten...perfect idle. I got on the road and it ran fine...no miss...full power....no CEL. Drove home without a hitch. Car has been running flawlessly since. I plugged in a code reader today hoping to get some insight on the problem. NO CODES! I assumed if the check engine light had been flashing it would have set one or more codes. Nada. Any ideas on what the heck happened? I would hate to take it to the dealer only to have him tell me there is nothing wrong.
