Maintenance/Repairs

the car is 7 years old, 30K miles, according to the mechanic there is a misfire,
the mechanic asked me if someone else had worked on the cylinder 1 before, because the coil for this cylinder.plug appears to be a generic one, does not look like the original.
The car had never had any issues and therefore no repairs. In the picture the coil in question is circled. He also wondered if the
issue is caused by bad gas. I drive 60 miles or less once a week.The engine
light came on once, for less than a minute when I first noticed a difference
in performance. I forgot to ask for the code.

I called back for the code and was told that no code showed up. As I understand
his diagnostic tool using special cases then told him that the issue is with cylinder 1. The picture was sent taken by the mechanic.
