A Call With No Problem Named
Sometimes all you get is the car. A missed call, then a text with the year, make and model. That is fine. It just means the job starts with diagnostics, not a part.
What the Diagnosis Found
A bad spark plug and coil on cylinder 2. Each cylinder has its own plug and, on this engine, its own coil. When one goes bad, that cylinder does not fire right.
The Job Record
What Usually Comes Next
The fix for a bad plug and coil is new plugs and coils. The record for this day shows the diagnosis, so this post stops there.

Questions
What does a bad coil do?
Each cylinder on most newer engines has its own coil. When one fails, that cylinder stops firing right. The engine runs rough.
Do I replace just one plug and coil?
Often just the one that failed, unless the rest are old. You decide after the quote.
What if I do not know what is wrong?
That is fine. This owner did not name a problem at first. A diagnosis found it.
