I have a 2005 accord for sale check engine light was flashing went to AutoZone plugged it in told me to change spark plugs and coils. I did that and the check engine light still flashing went back to AutoZone. Number one cylinder has misfire needs engine work. Transmission is good has ice cold AC tires are good front brakes were changedsix months ago. did a compression test number one cylinder has 30 pounds of compression needs new piston rings or engine swap everything else is good.
