How to idle speed increase after maintenance?

Before solving this question

You need to know who is this problem mainly related to?

Yes, that's it -- the throttle

Under normal circumstances, there will be impurities and air into the throttle valve during the engine intake process, and these impurities will accumulate in the throttle plate for a long time, and the impurities will accumulate more and more carbon after a long time.

When the throttle reciprocates, it will be subjected to resistance, and the engine computer will adjust the position of the throttle flip plate for a long time. That is to say, the position of the carbon deposit is used as the throttle body, which is equivalent to the throttle is not in place but closed to the position of the carbon deposit.

Over time, the sludge continues to accumulate, the motor opening signal is constantly updated and stored, and the opening is suitable for the intake gas blocked by the sludge, so as to ensure the current idle speed.

After cleaning the intake valve of the vehicle, the flap is still formed according to the original motion, which is equivalent to not being in place, but the difference is that the carbon has been cleaned away. Therefore, the intake volume will be more than normal, which will cause high idle speed.

So what's the solution? Generally, there are the following two points - 1. Most models will adjust the engine computer after a period of time; 2. Computer programming replaces the old data, so that the engine speed is immediately restored to the best target speed.

Of course, if you want to deal with carbon accumulation, you still need to focus on prevention, choose the full synthetic lubricant, you can more effectively prevent and remove carbon accumulation.
