Ignition coil problems

[JonZ]

Hi all, I'm new to this forum but have read through quite a few of the posts. I have an issue that one or more of you may have had and wanted to see about some possible guidance.

I have a 2004 Tbird. As several have noted, I have experienced noise from the rear end and ended up replacing the right rear wheel bearing - which solved that problem. I also had to replace the heater bypass valve which solved an AC problem.

However, most recently, I have had to replace three ingnition coils. First 1, then a second and today the third. When the shop replacex the first 2, they also performed a complete test of the fuel system and cleaned the injectors. I drove the car for about 10 miles after picking it up, got the blinking than solid "check engine" indicator - and back to the shop for ignition coil 3. In a discussion with the shop, they found a bulletin related to a coil seal issue from Ford for 2005+. So today they also added "seals". Has anyone else had this issue?
