  2.  While testing, never race the engine.
  1. avoid a prolonged engine compression measurement.

    Engine compression measurements must be performed as rapidly as possible.

  2.  do not run the engine when the fuel tank is nearly empty. This may cause the engine to misfire and create an extra load on the converter.
