This report presents the procedures used in a feasibility study to test properly maintained vehicles which had accumulated between 40,000 and 50,000 miles. The test fleet consisted of California certified 1979 automobiles obtained through random selection from private owners in Los Angeles and Orange County Areas. Each test vehicle received an incoming inspection and repair of minor disablements prior to testing. The test consisted of a diurnal heat build, less emissions, followed by the 1978 Federal Test Procedure. Vehicles failing the 1979 California standards received a tune-up, maintenance, and repair of malfunctions prior to a retest.
