So, on my way back from work on Friday, my "service engine soon" light came on. When I got home, I connected my scanner and got a P1416 code. Secondary air valve bank two. Fortunately, the valve on my '98 LS1 is very easy to access. $20 and 10 min. later, valve was replaced ( right outside Napa). 2 miles on my way home light turned off! I think this has been one of the easiest repairs I've done in a long time!
