2010 Accord V6 115K miles. no error lights yet. just noticed a bit of rough idle both when stopped in drive and in park. sometimes when i walk behind the car when its running and in park i can hear a "stumble" coming out of the exhaust. car hasnt stalled or anything yet. havent noticed lack of power while driving tho.

any ideas?

Have you notice MPG difference? could be an air leak somewhere? fuel filter need replacement? or maybe O2 sensor, Intake manifold leak, bad plug, bad wire, bad gas...

Does the tach move with this "rough idle"?

not that i have noticed. if it does its very minimal.

what about running a bottle of fuel system cleaner thru it?
