What happened before test 1?
What happened after test 1?
What happened after test 2?
Thx!

Before test 1. I drove 800 miles RT to/from SoCal Oct 2011, got a CEL because my kill switch wires disconnected and I reverted to key-off-on EOCing. I cleared the TCs. Drove the car 800 miles in local driving after clearing the TCs. Hadn't driven the car at all in December 2011.
Before test 2. After failing the first smog test, I learned the cat converter drive cycle on my xB is 15 minutes at speeds between 60 and 100 kph, the O2 sensor drive cycle is taking the car >40 mph, and the evap purge drive cycle starts 5 hours after the key is switched off after completing the cat drive cycle. So I drove up the highway between 50 and 60 mph for 15 minutes, drove back, and parked the car overnight. The next morning before the test, I drove around to take the miles driven since the failed smog test to >100 miles.
After test 2. I drove 900 miles RT to/from SoCal looking for a Gyrfalcon (missed seeing it), with no EOC, keeping the cat lit the whole time.
