Try to take it out and use some wd40. spray it well on the inside.. let it sit a little and see if that works.

or just get seafoam and try that instead. The barel on the inside should flop freely.

This. Same experience. My car started stumbling after a few miles after cleaning the ICV with brake/carb cleaner. I then also lubricated it (used PB Blaster on mine) and never got the issue again.

Agreed, that mechanism functions better lubricated.
