My 2000 Honda Civic has the check engine light on and i have taken it to Auto Zone so they can determine the problem with the computer and they told me it was codes P0300- P0304, which is misfire in all four cylinders. I replaced the spark plugs and the wires and the light is still on.
I waited to see if it went away and it didn't, so i took it again and they keep telling me its the same thing. I took it to a few mechanics and they said the same. They charge a lot to just see it and most of them told me that the problem might be different things.
So i was wondering if anyone knew what the problem might be.
