The purpose of the report was to determine the causes of high in-use emissions for 1981 and newer passenger car vehicles. The Virginia Testing Laboratory (VTL) of EG & G Automotive Research Inc. was to procure 100 1981 or newer vehicles (but no 1983 or 1984 model year Chrysler vehicles equipped with 2.2. liter fuel injected engines and automatic transmissions). The VTL subjected each vehicle to an initial idle screening and inspection and based on the results, to an Federal test procedure(FTP) and various short cycle tests. The vehicle then received corrective maintenance, reinspection at a Maryland I/M station, and a second sequence of tests. Of the 91 cars tested in the program, 88 passed the Maryland standard of 1.2 percent carbon monoxide (CO) and 220 ppm Hydrocarbon (HC) after the first series of repairs, two cars required a second set of repairs (i.e., new catalysts) to pass, and time ran out before the one remaining car could be repaired to pass.
