I'm Rena. Forty-four thousand kilometers. After cleaning the throttle and air intake. Idle a little and the fire will arrive 1500. Cann't come down

Hello, the car housekeeper team will answer your questions! Hello, first of all, I want to know, after cleaning the throttle, can the idle speed return to 800?

Then I want to explain that no matter what brand of car, the idling speed will be too high after cleaning the throttle valve body, because the gap at the edge of the throttle flap will increase the air flow after cleaning the sludge of the flap! So the idle speed will be high!

Generally speaking, it is normal if the idle speed can drop below 1000-20 seconds after taking a taxi!

If the speed shows no obvious signs of falling back, then you need to re-match the throttle!

20-50 engine oil will do, but personally, 15-40 is enough. If the viscosity is too high and the fluidity is not good, it will increase the wear! Don't be too thin Unless it is fully synthetic! 5W~40 can be used all year round! If you don't understand, ask again. If you are satisfied, please adopt it! thank you
