Hello, I'm Chris.I will do my best to answer your question fast and accurate using the info you have provided. Thanks for visiting Just Answer.
Do you still have a misfire?
Is it storing any fault codes?
Is the check engine light on or flashing?
No misfire now
The only code it had was for a misfire on cyclinder #2
Replaced coil & boot with new
TID 26, 2A & 2B
No check engine light
car has had a drop in fuel economy
Mode 6 data is a collection of if I recall the number correct, the last 400 starts so if you had a concern at any point in the past 400 starts then its going to show up on mode 6. Most techs do not even use mode 6 data because its not all that helpful in diagnostics.
If you just a coil fail then I assume you have high mileage. In that case make sure you have done a tune up using motorcraft plugs. Since the car is not telling you there is a concern via the check engine light then i would not suspect a engine issue at this time but recommend these below steps.
