      O2 sensoV way off.
      dang that intake air is hot.
      engine temp indicates its warmed up.
      TPSV slightly off.
      redo the link and sync per tech bulliten not service manual.
      ign timing is rather high for a warm motor.

          glad its running better.
          still does not negate the fact the O2 sensor voltage is way way out nor the TPS V is almost out of range.
          fix the last details and it will be sweet.
