DTC P0301-P0304 are cylinder misfires.
on 97 civics (except HX models) there is a service bulletin (99-011) that covers replacement of a faulty ECM that causes these codes to be thrown, but with no driveability problem.
emissions extended warranty covers this for 14 years / 150,000 miles.
if you have any fuel/emission related problems with a 95 accord V6, or any 96-97 honda (excl. passport) bring it to the dealer. they'll fix it for free.
i have 77200+ miles...
i already know that i had a misfire. we replaced all the spark plugs and such...
but its given me the same code TWICE now for a bad oxygen sensor...the SAME oxygen sensor.. i replaced the primary one ("A", up front under the hood) last night..and 40 miles after i reset the check engine light it came back on...that is my current problem. i bought the car used with no warrenty and i dont want to take it to a honda dealer and then fix it and lube and probe me up the ass b/c I DONT HAVE THE $ to pay them! im trying to avoid honda dealers at all costs!
