Abstract 271 vehicles from the 1981 through 1988 model years that failed their regularly scheduled I/M test received extra tests while still in the inspection lane. Those extra tests consisted of an immediate retest (i.e., a second chance test) and a similar test preceded by three minutes of 2500 rpm, no-load operation. Analysis of the test results shows that the three-minute, 2500 rpm, no-load preconditioning cycle added very little over simply an immediate retest for most of the vehicles in the study; however, that preconditioning cycle did have a significant effect in reducing the failure rate of those vehicles that exceeded only the HC standard on the initial test.
