ABSTRACT OF THE DISCLOSURE The present invention is directed to a system which reduces the loading of the vehicle engine when the manifold vacuum pressure is less than a predetermined threshold level without requiring action by the operator to effect this shedding of the load. In addition, the invention incorporates monitoring apparatus in the system, to provide indications of the operator's inability to maintain a relatively high engine operating efficiency as indicated by the number of times the vacuum pressure decreases below the threshold level. Also the invention provides an indication of the time that the vehicle is operated in this less efficient condition. The information is available to the vehicle owner at the end of the period of operation and thus enables him to determine the habitually inefficient employee-operator of his vehicles.
