I have a 2007 honda civic coupe. It is getting ash in my cylinder two spark plug bay. I don't have any ash in any other spark plug bay just cylinder two on the left side. If you have any ideas on what it could be please let me know.

 

welcome to the forum. may try some di-electric. looks like a clear jell. purchase from auto parts house to help keep ash from forming.

 

Thank you. And if that was yhe case wouldn't it be in all 4 spark plug cylinders not just one?
