Thanks for the great info! I had a ring job done by Honda dealer 3 years ago and the P0302 code fired again (a few weeks ago, after only 31k miles after the ring job). I replaced an oil fouled plug and it seems to be running ok after clearing the code. I also needed to add 2/3 quart oil between the last change at 106k miles.Yes, i have been with Honda for 13+ years
This is solid advice, Honda has issued a TSB ( Technical Service Bulletin ) regarding fouled spark plugs, i just recently finished a 2011 Odyssey that had DTC P0301 # 1 engine misfire and they used to have us just replace spark plugs 1-4, then update the PCM software to now go straight into replacing the piston rings.
For some reason only piston rings 1-3 are almost always affected, and we hardly see #4 go bad , i think we have only seen 2 since the recall/warranty extension has been issued that #4 misfire is recorded
I snapped some pics of the piston ring job i just did today
Take a look
