In addition to the HCHII in our household, my wife happens to drive an Odysey Touring. The Odyssey is widely documented to have this issue when in VCM mode, with 3 cylinders shut of. It's refferred to at ODYCLUB.COM as the "2100 rpm drone"

It hasn't bothered me enough to have them work on it. At odyclub many report the problem coming back after time...

Drive another HAH and see if it has he same issue you are refferring to. If is does have the same issue, and it is not too intrusive, it may be considered "normal" by Honda...

By the way do you work for McDonalds corporation or somthing like that?
