Propane gain values have been collected from 292 Portland Element III (1975-77 model year) vehicles along with as-received FTP and idle test emission measurements. This data is used here to compare the expected failure rate, errors of commission, and the amount of FTP excess emissions identified if one of two sets of idle values or one of four propane gain values had been used as a cutpoint to screen the vehicles in the sample with high emissions.
