Default S70 rough idle sitting in traffic

99 S70GLT with 99K miles.

Sitting in start/stop traffic today for about 15 minutes, the engine started to idle rough, almost stalled, this went on for about 30 seconds, then cleared up. AC was on, no warning lights came on, she did not notice if the temp was above normal. Drove home, no problem, and no problem starting this morning.

The MAF was replaced about 3 years ago at 81K miles. That was just about 2 weeks after the ETM software update was done.

Recent tune-up, car has been running great.

Could this be the first sign of an ETM problem, or something else?
