      Sorry for the delay. I've been out of town for work a bunch lately. Anyway, I changed the fuel filter, cleaned the MAF with MAF cleaner, and cleaned the throttle body with TB cleaner (I recharged the K&N air filter for good measure as well).

      The good news: Lag is gone. The bummer is since I did all three at once, I'm not sure what the exact cure was. I suppose it doesn't matter, because she needed all three regardless.

      The bad news: the SES came back (not sure of the code yet).

      Possibility: I did find a small leak in the PCV hose at the knuckle that connects to the back of the TB. I tried repairing it but the seal broke back open the first time under WOT. The GM Parts Center wants to charge me $104 for the whole PCV hose. I work for a supplier so I am familiar with the "what it costs to make vs. what the OEM sells it for" markup, but damn. I'll repost after I replace it and see if the codes stay away.
