The report presents the results of an emission testing program which was conducted for EPA in Washington, D.C., under contract. In the test program, 1980 and 1981 model year vehicles which failed the Inspection and Maintenance (I/M) test in Washington, D.C. were given two or three series of emissions tests. Each series included a Federal Test Procedure (FTP), a Highway Fuel Economy Test, and the following short tests: 50 mph cruise, four-mode idle, engine restart idle, and loaded two-mode. In June, 1984, EPA became aware of some quality control problems which were evident at the D.C. inspection stations. These problems may have caused some of the vehicles which were participating in the project to be inappropriately failed during the initial inspection or inappropriately passed during the reinspection. Analyses described in the report evaluate the decisions made by the inspection lane, and compare the effects of I/M on the whole group of cars with those of subgroups that have had suspect cases removed.
