My car has 120000 miles.
My car has an automatic transmission.

To start you will need to replace the valve cover gasket and clean out all the oil out of the spark plug tubes. Then you will need to replace every coil boot that got oil on them. Once this is done then you can clear the codes and road test to see if the misfire goes away. If any cylinder still misfires then you may need to replace the coil for that cylinder.
