Z stuttering on warm start

[buddahson]

Had multiple instances where the Z stuttered on startup today. It starts and then nearly dies before returning to a normal idle. I think the engine was warm in all instances. No error lights or other signs of trouble. First thought was dirty air filter. They were dirty, and I cleaned them up a little. Seemed to help at first but then the issue came back. Car runs ok after a minute.

The car is a 2009 and is stock. 11500 miles. Oil, coolant, gas and temp levels normal. Garage has been dusty the past few days which is why I lean toward air filter. Anyone have other ideas?


Thanks,
Matt
