Vehicles in daily use, the engine produces carbon is normal. Regular cleaning coke is necessary, but in fact this aspect is not an absolute fixed period, because each car owners driving habits, road conditions are different, can not be generalized. Carbon deposits inside the engine can not be prevented, but the correct use of the car and driving habits can effectively reduce the production of coke. According to the manufacturer's instructions to choose the model grade of gasoline, but need instructions on behalf of the grade of gasoline octane gasoline, reflects antiknock gasoline, gasoline and gasoline quality label can not be on a par, good reputation proposed to the regular gas stations, as crude oil and refined process reasons, coupled with commercial gasoline sold in the market is not a high quality gasoline, gasoline components containing sulfur, phosphorus, in particular a high olefin content and oxidation stability is poor, In the work of internal combustion engine is oxidized olefin condensation of the gum, and the engine crankcase gas and the intake of dust particles in the collection, the throttle body, intake manifold, etc. connected to form carbon. Also driving habits and conditions of use is also very important, "high gear speed" driving bad driving habits can cause incomplete combustion gas mixture easy to generate carbon; avoid prolonged engine idling for a long time at low speed vehicles should always run a run high-speed, high-speed driving can make mixed combustion, improved fuel economy, if you do not often run high-speed, on the road in the city, "low-grade high-speed" can also reduce the formation of carbon deposits to restore the oxygen sensitivity of the sensor, clean the spark plug electrode between the surface of the catalytic converter and coke.
Their hands and clothing, we will be almost 5000 km throttle car wash, which is the regular maintenance must be done, wash the throttle relatively high cost, high-end car needs a few hundred dollars, and dozens of private cars also need Yuan cleaned once. You can do it yourself and enjoy the fun of DIY and save a lot of money, why not do it?
Category: one is by cable to control the semi-mechanical semi-electronic throttle body, one is through the sensor to the signal that is fully electronic throttle, through the computer, with the intake air and sensors to calculate the angle of the throttle valve opening angle.
[Harm] without access to clean throttle
First, the time to clean, can cause the throttle opening degree of error
Second, the impurities can cause air into the engine combustion chamber.
The result of these two engine abnormalities, mainly idle instability; sudden instant high speed stall (close the throttle suddenly feeling); powered down; severe cases can cause difficulty in starting and increased fuel consumption.
The first step: preparation tool.
10 small wrench a (removable battery terminals), a large Phillips screwdriver a (removable intake elbow), T30 wrench inside a flower (removable  Throttle Body   ), carburetor cleaner bottle.
Step two: Remove the throttle intake pipe
      Removing the throttle intake pipe
      Removing the throttle intake pipe
       Gently take out the intake pipe
The third step: Unplug the wiring harness connector throttle
       Disconnect the wiring harness connector throttle
Step Four: Remove the   Throttle Body     

   Removing the throttle body 1
       Remove the   Throttle Body  2
       Remove the throttle body 3
Step Five: Remove the throttle body for spray.
       Remove the throttle body
       Spray cleaner
       Do not ignore the details
Activities in accordance with the direction of the throttle hand during flip for thorough cleaning.
Step Six: Place a clean install throttle as (tighten the three bolts, plug harness plugs, install the intake pipe):
       Place a clean throttle reset
Step Seven: throttle position sensor for initialization
