I know the code is misfire cylinder 5. The plugs are new the wires are new and the cap and rotor is new. Even being new I check them any how. The plug was carbon-ed up bad so I replaced it. The wire was check for resistance and it checked out good. The cap was checked and it checked out good. Now I'm lost. What else should I check. By the way the compression is 125. I look forward to your responses.
