the 3100 does not have the capability to display live data. head to a local shop with an OTC or Snap-on scanner and tell them your cam retard is out of adjustment. I don't think any Equus scanner can to do it I think. It is a gm enhanced PID. for a '99 unit they will raise the rpm's to 2000 and 4000 to check the measurement. and adjust the dizzy as needed to achieve a 0.0° +/- 2.0° setting.
