the drive cycle is drive 5 mins at 45 mph without touching brk slow to below 25 mph then back to 45 mins again for 5 mins all without touching brk pedal. the o2 might take several cold starts if the heater circuit was the 02 code.this all assumes the issues were repair correctly

I realized that the O2 sensor when not ready can cause the catalyst monitor to not run & report as not ready. So most likely my problem is with O2 sensor - what is the drive pattern to get that ready?
