One hundred fifty light duty vehicles from model years 1979 through 1981 were obtained from the public, in the Los Angeles and Orange County areas. These vehicles were tested as received, for exhaust emissions utilizing the 1978 Federal Test Procedure, the Highway Fuel Economy Test (HFET), and four short mode tests. Thirty-one 1981 vehicles received an evaporative emission test using the sealed housing evaporative determination (SHED) technique. Thirty of the one hundred fifty vehicles received restorative maintenance and repairs and additional testing.
