  • Misfire under load

    -The car starts up is without any problems, but under load has a misfire and once warmed is more pronounced.


    Checked a few things today to see if there's anything I could do to fix it:

    Removed and checked the plenum to check for leaks (none found)
    Checked plugs and wires for correct resistance measurements (all checked ok)

    It was getting late so wrapped it up and tomorrow going to check TPS and CPS.

    Any other recommendations?

    Also check for AFM going bad.
