I completed the drive cycle but only got 3 out of the 6 monitors in a ready state. Looks like I will have to redo the drive cycles again. I just need one more to squeak past on the smog test! At what point do I have to start replacing parts such as the O2 sensors or EGR valve? The OBD II scanner does not return any codes and there are no stored faults.

Thanks for the pointers!!!!
