They asked me the first time through if i had reset the ecu (which i did that day when i put in the o2) and they told me to come back in a week because it takes a while for the ecu to read everything. but i tried and it didnt work. if anyone has any answers for me i appreaciate it.
not ready is a trouble code that populates after reseting the ECU.. what is required to clear that code is different on all cars... but it is normally a sequence of events like multiple starts and stops, multiple variations in speed, and maintained speed for a short period of time at like 50+ mph...
i imagine if you drive around your town, make a couple stops, then go for a drive on a highway it should be enough to straighten that out.. it is as far as i know NOT something as dramatic as 300 miles...
