Forester 2.0 washes the throttle valve, and the throttle valve starts to open at 2000 rpm in the morning and slowly rises to 2500 rpm. It will last for a while, and then slowly drop a foot of oil. Is there a problem? Hello, I'm a question-and-answer expert from cool car. Your question has something to do with idling. If the idle speed is unstable, first check the carbon deposit on the throttle body and idle valve. Excessive carbon deposition will lead to unstable idle speed, which can be solved after cleaning up carbon deposition. Secondly, check the sealing condition of the air intake system. Air leakage can also lead to unstable idle speed or high idle speed of the engine.

I hope my answer can help you.
