If the engine is idling rough, the coil-drop test is very easy for you to do! And as others suggest, find a good independent mechanic rather than rely on the services of the 'stealership'!will have to ask the dealer about that. I don't think it is something I can do, but have seen it discussed a lot here.
I'm guessing spark plug "6" loosened and the honest grease monkeys @ the dealership told the service manager LOOSE spark plug who then turned it into a major cash upgrade for HONDAWe changed the timing belt around 135,000 so we are ok there for a while. We are due for spark plugs though. We are pretty good with the maintenance and good with driving habits. Thanks for your reply.
