Hi I have a 2008 v6 6 speed accord, when im coming to a stop for more than a minute or 30sec ,the engine starts miss firering. there is a little bit of oil in the spark plug tube in the back right cylinder (if you are facing the front of the car) just changed coils and spark plugs cleared the code and for now its fine. don't really know what is wrong with it. does anybody knows or have clue??

 

Just to clarify, the problem is completely gone after the coil and spark plug change?
