Those hondas have been known to have valves that stretch or cup at the head of the valve. When they do...all the clearance dissapears, and I have seen them stretch to the point they hold a valve open and cause them to burn . If a valve is not fully closing , which is what I was reffering to, then the compression will be lower on the offending cylinder.
That would cause a power loss/velocity change on that cylinder, setting the premise for the missfire counter to set a code.
Fact is stranger than Fiction
