Might be a false alarm on my case. When I open up my air filter, there is maybe a 2mm thick dust collected. I change out the filter and the idle return to normal. Checking back on my service record, it seems I didn't change air filter for almost 24k km. And my work place is in dusty industrial area, 8 hours parking and you can start drawing on the seat. Anyway, will keep monitoring if the idle issue really is false alarm.
