i have failed a smog test twice. both times saying o2 sensors are "not ready". i have put new original o2 sensors (not universal). no check engine light. car drives fine. has slight low idle. have noticed a small crack at the connection of the upstream o2 sensor in the exhaust manifold. car still drives fine. no check engine light. check engine light does come on and off when i turn car on. i have no radio (lol)
i have been told to "just drive the car around and the o2 sensors should 'turn on'..." i have been driving the car for months now... even trying to do the recommended speeds (24mph for few min....45-50mph for a few min...idle for a few min then 25mph for a few min....) have connected obd reader comes up "no codes"
PLEASE ANY INPUT HELP WOULD BE GREATLY APPRECIATED
