This paper describes the results of a follow-up survey with participants in EPA's Emission Factor Testing Program. The survey was conducted in the form of a questionnaire which program participants were asked to complete and return about one week after their car was tested and returned to them. The questions pertained to the efficiency of the lab personnel and the performance of the participant's vehicle after it had been tested. Some comparisons are possible in that almost half of the vehicles received maintenance as part of the test program. The results show that practically all participants felt that they were treated courteously and efficiently by the lab personnel. The vast majority felt (whether or not their vehicles received maintenance) that their vehicle displayed either no change or an improvement in its performance after it underwent testing. Compared to owners whose vehicles were not maintained, a greater percentage of the respondents whose vehicle received maintenance felt that there was an improvement in its performance. Of the respondents that were not satisfied with the present performance of their vehicles after maintenance, most were dissatistifed before the maintance and testing had been performed. Overall, the information from this survey concludes that the majority of participants were satisfied with the testing and the maintenance actions that their vehicles received.
