Emission and fuel economy tests were performed on a sample of one hundred individually-owned 1975 and 1976 model-year light-duty vehicles in the Chicago metropolitan area. Vehicles manufactured by Chrysler Corporation, Ford Motor Company and General Motors Corporation were represented somewhat equally. The purpose of these tests was to investigate emission and fuel economy performance of typical in-use passenger cars and to quantify the individual and combined effects of any observable defects, disablement and/or maladjustments on exhaust emissions and fuel economy. The investigation followed a test plan which consisted of two portions. All vehicles entered the first or Restorative Maintenance Evaluation portion. Certain vehicles that received a major tune-up and passed Federal Exhaust Emission Standards upon completion of the first portion proceeded into the second of Selective Malperformance Evaluation portion. The first test in the plan was conducted with the vehicle in its as received condition. Up to three additional tests were conducted in the first portion each of which was preceded by a restorative maintenance action. Vehicles that proceeded into the second portion were tested five or more times. Each of these tests was preceded by a selected maladjustment. Each test point consisted of the 1975 Federal Test Procedure Economy Test and five short cycle tests. A modest driveability evaluation was also included.
