The Environmental Protection Agency conducted a survey of 6,586 light-duty motor vehicles for tampering with emissions control devices. All vehicles inspected were classified into one of four mutually exclusive categories: tampered (at least one control device removed or rendered inoperative), arguably tampered (potential, but not clear-cut tampering), malfunctioning, and okay (all control devices present and apparently operating properly). The results were: tampered - 20%, arguably tampered - 27%, malfunctioning - 1%, and okay - 52%. The survey also found that 9 percent of the unleaded vehicles were subject to fuel switching (using leaded gas in vehicles requiring unleaded fuel).
