Ford Repair Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.
What brand coils and plugs are you running?
Have you monitored the coils to confirm they are getting full battery voltage?
My first recommendation is to use better products as the failures continue to occur. You really need to be using motorcraft plugs and coils. The 2 you mentioned are very cheap and poor quality. I can not even guess how many of those I have had to remove and throw away and they still looked new on the customers car.
Next which ever coil fails next, verify its getting battery voltage to rule out that circuit to blame. Next would be to use a scope or noid light to test the ground pulse to the coil to see if the wire is grounded constant or to see if the PCM COP drivers are faulty and grounding the coil to often and overworking it.

Coils are going to fail, any brand. Its how long they last and can operate at 100% that is important. I have heard the motorcraft coils are not good as well when talking to customers and when wasting my time reading blogs. Most all of those are customers over 70k on there vehicle mad because one or more coils have failed. Coils are going to start getting weak in the 70-110k range.
Can you create the tick in park or in gear or while brake torquing. Meaning anyway to make it occur when not moving?
Thanks, ***** ***** touch.
