I have some suggestions....
I have gone through the SAI readiness problem several times. The drive cycle you show is accurate with a few exceptions.
Start the cold engine and idle for 1:40 (not the 3.5 minutes). You will hear the secondary air pump shut off. It is a high pitched whine and it is obvious when it stops. Then, do your cycle. Important: Do not exceed 3000 rpm at any time during the drive cycle.
That may clear your SAI readiness.
If not, try this- I read this on this board and it works:
Again a cold engine. After a brief idle, increase the RPMs to 2700 and hold for 90 seconds. Done. Then check for readiness (or check the next day before a restart).
As stated, the fuel in the tank must be between 1/4 and 3/4 full.
If any of these work, immediately go to smog check.
Good luck.
