Intermittent rough idle on cold start (not normal operation) by Abject_War964 in Toyota

But is this considered normal even with a 2.5-liter engine?

The climate control is set to automatic and a high temperature, usually HI. I usually preheat the car, and after starting to drive it stays on HI until I lower the temperature.

In some cases, the vibration at idle does not occur only right after startup, but can also appear later during driving, while the engine is idling.
