Will oil deterioration affect the throttle?

Hello, bad oil will cause air leakage in the valve, and then it will lead to unstable idle speed and aggravate parts wear. It is recommended to change the oil on time for 5000 kilometers or half a year, whichever comes first. I hope my answer can help you. If there is something wrong with your car, ask the car mechanic. 4S shop professional technician, 10 minutes to solve.
