2023 Hyundai Ioniq 5 — rough idle disappears just above idle speed

HybridMiles528Community StarterMay 5, 20262023 Hyundai Ioniq 5 LimitedTexas
2023 Hyundai Ioniq 5 Limited, about 74,000 miles. Idle has a slight shake once fully warm, but 100–200 RPM above idle it smooths out. No major loss of power. Would you look at mounts, vacuum leaks, ignition or fueling first? I am in Texas. If I figure it out I will update the thread.

If it were mine, measure it if you can. Two cars can feel identical and have different causes.

If it were mine, I would want a real battery/charging test, not just resting voltage, before blaming a module.
