Spark Plug Tube Seals Leaking Engine Oil
A very common problem with the 1.7L equipped Honda Civic DX, EX, or LX is engine oil leaking into the spark plug tube from the valve cover spark plug tube seals.
Depending on how much and how long the spark plug tube seal has been leaking, the ignition coil's spark plug boot and the spark plug could be swimming in engine oil, which will cause the ignition coil to misfire.
If you encounter this, you have two options. The obvious one is to clean the oil off and reuse. The other one is to replace the ignition coil and the spark plug with a new one.
The only problem with the first option (the cleaning off of the oil) is that it isn't always a sure cure. So, if you clean and the misfire continues in that cylinder then you'll need to replace the ignition coil (because the boot is not replaceable).
