Please ask questions &; Quot Throttle opening index 5&; Quot why do you want to clean it?

Throttle opening is throttle angle, and 3 or 5 is the minimum throttle opening. The EFI car only has a throttle. After the throttle is dirty, the minimum opening cannot be reset, and the engine intake cannot meet the needs of the dirty throttle, which is beyond the range of throttle adjustment. Therefore, the idle speed will shake and the waste engine oil will come out. Just compare the new car with the two kinds of throttle that have not been washed for more than 65,438+00,000 kilometers. I always wash the accelerator myself, and it costs ten yuan to wash it once. Remove the throttle body and use 3m cleaning agent, which only takes one hour before and after.
