Don't FORGET to use a Computor Memory Saver!!!! or you will loss your radio and need a code to reset it. The CMS cost about $10 and plugs into your cig lighter, it comes with a 9v battery. This has to be done any time you un-hook your battery.

Does it drive ok? You may need to just clear the codes. Try disconnecting the battery and connecting again this will reset the codes. If it comes on again let me know and I can try to help some more. Thanks

Engine lights comes on checked code and po300 comes up


that's a multiple cylinder missfire code(random). Has it been a bit shaky recently? if you haven't performed a tune up recently, it's time to do so. replace plugs, wires, and in some cases, the distributor cap and rotor if equipped.

My 96 honda accord is giving me three different code readings they are: P0303 cylinder 3 missfire, P0302 cylinder 2 missfire & P1300 multiple missfire detected, How do I fix this problem?


I would start with a full tune up. If it has never been done then that is the best way to start. Make sure that you gap your plugs. NGK plugs are the best for any and all Honda's. Let us know how it goes.
