The person commenting about all hondas with a 3.5 liter engine with the VCM system installed. Do all have this same problem. No matter what year. I have a 2016 Honda Odyssey with the 3.5 liter with the VCM system. At 118,000 My rear bank spark plugs started Coking up causing a code P0301 and P0303. Had to remove the rear Cylinder head for those 3 cylinders. Remove the pistons and replace the rings. Then reinstall everything. Honda wanted to charge me $5000 to put a Band-aid on this issue. And said they could have it ready in 2 days. It's not possible if you're going to do it correctly. The best way to fix this is go out and buy VCM muzzler. It will stop the VCM system from operating.
