After replacing fuel injectors a few weeks ago because of a P219A code, injector failure on cylinder #1, It became obvious that dirty valves is a real problem for this newly designed Honda V6. Not much being said about it. I think that awareness is needed or pay the price later. Hence the reason for starting an a thread to discuss ways to combat it. I painstakingly scraped valves and used valve spray cleaner to help dissolve it. The engine is running good now after injector replacement and valve cleaning. I believe that dirty valves may be the reason for the hesitation some people are having issues with.
