Having trouble getting 5 of 8 monitors ready for inspection. Catalyst, Evap System, o2 sensor, heated o2 sensor and egr systems say monitors not ready. I have done multiple days of different drives cycles to reset the monitors with no luck.

There are no MIL indications on the dash or with a handheld datalink unit. Any ideas on what I need to fix or how to reset the computers would be great.

Thanks,
