      i have a 2004 accord with 109 on the clock and the issue i have is i kept getting multi check engine lights for misfires found out there was a reflash to the pcm to fix that issue but honda tells me it only was to help the computer rethink how it accepted the misfires which i think is bs

          Do that but also know that your gas mileage won’t be as good in the winter for a variety of reasons, in fact if you do a quick search using the search function at the top of this page you may see my comments on that, if not I’ll repost them I’m just short on time today sorry.

            thanks eric i just finished up today cleaned the holes did a power balance test same drop on all 6 cylinders so who knows im hoping it improves some what over the old 11 or see how much of my taxes i can soak in fixing it instead of paying it off lol its

              Great to hear that your EGR cleaning fixed your gas mileage issues. Sounds like you are getting around 20 mpg vs 11 mpg, if I did my math. right. My 05 V6 gets around 21 mpg city driving. Just remember that winter blend gas and short trips will have an affect on your gas mileage. That generation Accord with the V6 is a fine car IMO. Any other issues/questions please post and I am sure someone can help.

                    BTW if you’re also having transmission issues this will also effect MPG.

                        That is true about the gauge and it’s due to how the circuit works so there really is nothing you can do about it unfortunately.

                              Do you have a scan tool to look at fuel trims?

                                  There is a few threads in the Tool Section on scan tools if you wanted to do a search.
