Okay, here is the scoop!
My local dealership worked with Ford Engineering and they checked all of the items that could have possibly caused this issue.
1.) They pulled the driver's seat and checked a harness under the seat that ties in with the
Perimeter Security System. They disconnected and reconnected it.
2.) They reprogrammed the PCM according to the TSB and replaced the Idle Speed Control
Valve and checked all of the grounding points on the Engine Wiring Harness.
So far, I have not had any incidence of this issue, including the 'hiccup' at speed on the highway. I drove the car right at 600 miles since last Tuesday when I got it back and have not had a single 'Hard Starting' issue either.
So, with them checking all connections and reprogramming and replacing the ISC, it looks like they fixed it. But, only time will tell.
Hey, I love my ST, so there are no gripes from my end.
