Rav4 Low Idle Abnormal Noise after Throttle Cleaning

Hello, car owner, because the throttle is dirty, when accelerating at ordinary times, ECU judges that it is necessary to increase the opening and closing angle of the throttle to reach a certain air intake (and record it in ECU)! After cleaning the throttle valve, the stolen goods are removed, and the air intake increases accordingly, resulting in an increase in idle speed, abnormal air intake, unstable idle speed and loud noise. We can turn off the negative electrode of the battery for 5 minutes and then turn it on, so that the ECU can return to zero, and then the idle speed of the car will return to normal, the zero time of power failure, navigation radio channels and so on. ...

After the road test, the abnormal idle speed disappears, and the speed-up response is quick and powerful!

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