Do you definitely need all monitors in ready state? In NY we are allowed to have 1 monitor not ready to pass

Yoda - make sure your battery and alternator are in good condition. If you do disconnect and/or change the battery, you'll need to go through the drive cycle madness again.

What in the world did you do to your car that made it un"ready for smog"?

In CA all monitors have to be ready for a gasoline car. Diesel you can have one of the monitors not ready.

The car won't pass smog because the readiness monitor for Oxygen Sensor is in an "incomplete" state. This means that the car/ecu has not completed the self test at this point. I've driven the car close to 800 miles and still no luck.

@pfan The battery is original, but is in a good state. One thing I did notice is that while driving it's charging around 14.4-14.7v.

@JW911 Nothing! It's the darn computers! Very frustrating..

Given the car is stock, Porsche is obligated to warranty all repairs for 8 yrs or 80,000 miles to ensure it passes emissions requirements. Give it to the dealer and they should diagnose and repair for free. Question: did you fail a smog test or did you self diagnose using your electronic toy in advance of the smog check? Seems like you are putting yourself through a lot of gyrations and agitation when you could just bring it to the dealer. If you haven't done anything to the car to make it unready for a smog check, I don't think any amount of driving and resetting is going to fix this. The root cause needs to be addressed.
