I think - help me out Redbull - these are the ones with VCM. The cyl the PCM "shuts" off seem to foul the plugs. The software update is suppose to slow or stop this fouling.

Yes, this can be due to the VCM.

For the 8th generation Accord V6 (2008-2012), there been many reports of one or more spark plug fouling due to the way the VCM system operates. VCM is Variable Cylinder Management. Depending on the driving conditions, the Accord V6 can go from 6 cylinders, to 4 or 3 cylinders for fuel economy. Supposedly due to the way the VCM operated, certain driving conditions could lead to an overly rich mixture in one or more cylinder, which may cause the respective cylinder spark plug to get fouled.

Honda Worldwide | Technology Picture Book | VCM

Honda's general fix was normally to just changed the fouled spark plug(s) and update the ECM/PCM (computer) software. Sometimes, some other part(s) in the system (e.g., solenoid valve, etc.) may also need replacement upon further diagnosis.

Once again....I've always said Redbull has some "mad skills" and knowledge....

I can't even begin to think of everything I've learned just from reading his posts here, and "other" places......Thank you!
