   who do not know Brad, his car is equipped with an electric clutch servo

   readings are not correct, the servo unit not function properly and he
   cannot drive it.
   Here is the Setup:
   Pro Comp Low Profile DistributorA
   Matching CoilA
   No MSD 6AL and no Tach Adapter
   Here are the symptoms:
   Engine Runs Perfectly
   At idle, it shows 200 RPMs.A A
   Blip the gas and it jumps up appropriately then rests around 1,000
   where it should be for about 3 seconds, then drops back to 200 RPMs.A
   The alternator was changed at the same time, if that is relevant.
   My MSD setup was years ago and I needed the 6AL and tach adapter to get
   mine working. Not sure how it is now though. I am going to visit him
   Saturday to help diagnose/fix it or swap his distributor back to the
   Mallory.A
   Anybody have ideas as to what might be wrong or suggestions on how to
   best troubleshoot it?A
