Hey everyone. Im new here and had a question. For the past few weeks once in awhile my check engine light would flash for a few seconds and shut off.. sometimes it would hesitate and sometimes not. Today I was driving home the the check engine came on and stayed on. Hesitating the whole trip home. When the rpms would hit about 3k, the light would flash and my truck would hesitate like crazy. I just took it to advanced and ran the scanner. It said misfire on cylinder 3. What is causing the misfire? I know it could be plug or wire, but whatelse? Also, which is cylinder 3? I would like to check and see how the plug and wire look. Any help would be awesome and thanks for the help.
