How does Peugeot 307 2.0 clean the throttle?

There is no special restriction on the throttle. Generally, it will be cleared when the idle speed is unstable. It is related to the air environment of the car, the type of engine oil used, the interval between changing air filters and driving habits. Most people only clean the throttle after the working conditions begin to deteriorate (unstable idle speed, obvious engine jitter during cold start). You can find a familiar repair shop and regularly check the throttle opening with a computer (generally free). If the opening is less than 5%, cleaning is not required. More than 5% can be cleaned.

1. First of all, if there is a plastic heat shield on the engine, it needs to be removed first.

Remove the hood and you can generally see the throttle. There are some air pipes around the throttle, which need to be removed, and the position of each pipe should be clearly recorded.

2. After removing the air pipeline on the throttle, you can remove the whole throttle. Trent's throttle is fixed on the engine block with four bolts, and we can quickly remove it with suitable tools.

3. The side of the throttle near the combustion chamber is generally dirty, and the black carbon deposit mark is the main part we need to clean.

4. Cleaning the throttle is mainly to remove the carbon deposit on it. We can use special throttle washer fluid or cleaner. It should be noted here that the cleaning principle of this cleaning agent is to dissolve carbon deposit, and its composition is harmful to human body. It is best to wear gloves and masks when cleaning.

5. Spray the cleaner to the position with more carbon deposits on the throttle, and wait for about 5- 10 minutes to dissolve the carbon deposits. Using brushes can speed up the removal of carbon deposits.

6. When you see that the stain on the accelerator has completely dissolved, you can wipe the detergent inside the accelerator with a clean towel. The picture above shows the clean back of the throttle, with no traces of carbon deposition.

7. Install the cleaned throttle valve on the engine block according to the original position? Then install all the air pipes to complete the whole process of cleaning the throttle. After all the hardware is installed, throttle needs to be initialized.
