  • -20* Spark Advance.

    Nikon and I were out crusin sunday night....we hooked up his laptop w/ the OBDII software to my car...

    it said my spark advance was a NEGATIVE 20 DEGREES.

    -20*

    we hooked it up to his and his was 12* (12 degrees).

    Could this mean bad plugs???? LOL (most likely right?)

    correct that 12 to a 24 ;) even if its not the plugs you got alot of miles, well, kinda you need new plugs anyways....maybee new wires also?..
