What is your question?
I have a 99 volvo s70 that i had to disconnect the battery to replace the o2 sensor on and when i went to get the emissions done on it. It failed saying that i needed to put more miles on it. So i put 100 miles on it and it stilled failed. I just want to know how many miles do i need to go for tne cycle to pass

Hello, completing a "drive cycle" for diagnostic monitors to be set for emissions testing can be frustrating! There is no "preset" amount of miles to drive, however, there are certain things the engine's processor is looking for to validate all systems. Here is a good article about it here on RepairPal: https://repairpal.com/drive-cycle-issues
