______RPM_MEAS__MEAS__MAX_AVE_MEAS__MAX__AVE__MEAS _MAX__AVE__MEAS
15mph_1768_14.30__0.80_|_88__21___22__|_0.52__0.06__0.01_|_704__150__167
25mph_2922_14.40__0.50_|_53__13____6__|_0.50__0.05__0.24_|_738__136___87

With a stock cat, people generally fail the sniffer part of the emission test because there is something wrong with their car.
