I bought this new in Minnesota. After one year I added Long Tube Headers, hi-flow CATs, and Corsa Sports. It has a few track weekends on it.

2.5 years ago, prior to moving to CA, I had all original parts put back on. When I got here, a friend tested it and it has a bad O2 sensor. He replaced. No matter how what "drive Cycle" we tried, we could not get CATs to "complete". I took it to a Chev dealer. I paid one of the guys to get the drive cycle it and its CATs completed. It was smoged, and it passed. Until 2 weeks ago when a new smog was needed.

A few months ago, while in storage in my garage, I had forgotten to put the trickle charger on it, its battery went low and ECU reset 8-O

Same friend (Master Mech and CA Star rated) tested it. There appeared to be some lag time in one of the O2 sensors, so we replaced them all the be safe. I tried completing the drive cycle, but the CATs will not complete. Needless to say, the CATs and the exhaust system have less than 10K on them and the O2s are new.

Please help if you have actual knowledge of what "drive cycle" I need to use the get the CATs to complete so I am CA legal again.

Thanks.

Here's some info I posted awhile back. Not at the shop now to see if the 2006 procedure is the same as the 2009.
