2004 honda accord v6 at fuel consumption issues

[fitone]

I ran across this DIY for cleaning the EGR passages. The car shown is a 2003 Pilot, but very similar if not equal to your 2004 Accord. Hope this helps. Note that amount of carbon built-up on the Pilot is nowhere near what your picture indicated. Keep us posted on the affect to your gas mileage.http://www.piloteers.org/forums/18-maintenance/25692-diy-intake-manifold-egr-port-cleaning.html
