Car was put on computer at advance and showed multiple misfire??? What can that mean?? A slight tap from rocker arm on upper engine. I was told it could be my wires, plugs, or a rocker arm, if anybody can let me know what it can be. If any questions please let me know @2515812311...

Well my girls grand prix had the same diagnosis , but her head gasket was leaking also .. so I when ahead and took everything apart got to the heads cleaned them up well . and noticed small cracks where the spark plugs enter. That's the worst possibility . Yes it could easily be as simple as spark plugs or wires causing the computer to cause a multiple misfire. the slight tap maybe try oil change first.
