This report presents testing results which were gathered to determine the suitability of existing I/M testing scenarios to a Ford car with computer based emission control system. This car had a microprocessor based three-way catalyst as well as computer controlled spark timing, exhaust gas recirculation, charcoal cannister purging, air injection, and altitude compensation. After suitable baselines were established, various components were made inoperative in the emission control system. Complete FTP, HFET, New York City Cycle, Federal Short Cycle, and I/M tests were run for each Vehicle Condition. Methane measurements were also taken during the later stages of the testing program.
