I got the 77 from the ECU.
Since I need pass the emission to get the new stick, I reseted the ECU before I went to inspection.
But the test showed that several sensors are "not ready".
They suggest me to drive the car for a while and come back in 15day to get a retest.

Does anyone know how to sucessfully pass the retest without fix the rear O2 sensor?
How many mile do I need to drive? Currently I drive on the local below 40MPH since I was told that engine light is easily on when driving and quiting from high speed?

Really need you Help!

thanks
