Last November(11/2016), I bought this used 2000 QX4.
The guy who sold me this car, doesn't know much and doesn't speak english(he spokes Spanish) and car was sold as is.
Anyway, it runs fine and no leak nor no error codes nor smoke.
Engine runs very smooth and like it.
However, I drove almost 3 and half month(2/2017 now) and almost 3000 miles. Yet, when I check OBD, it never ready the driving cycle for SMOG check up in California.
Does anybody know why? or how to make it ready?
Thank you guys in advance.
