Bydf6 throttle will automatically rise.

Hello, there are several reasons why the throttle automatically rises.

First, the idle motor and throttle are dirty with carbon deposits and can be cleaned, but the idle motor needs to be replaced.

The second is the vacuum leakage behind the throttle, such as the leakage of the sealing ring of the injector, the leakage of the interface pad of the intake pipe, and the electromagnetic normally open exhaust gas. These points can be sprayed with carburetor cleaner where you suspect. If there is air leakage, the engine speed will change obviously.

Thirdly, the signal voltage of the throttle position sensor fails, the sensor signal voltage changes nonlinearly, and the intermediate signal is interrupted, so the decoder needs to read the observation data of the data stream refueling door.

The above points suggest that you focus on going to the repair shop for inspection and maintenance.

I hope my answer is helpful to you. If there is something wrong with your car, ask the car mechanic. 4S shop professional technician, 10 minutes to solve.
