Does Opel Astra need a special computer to clean the throttle in 2006?

After the throttle valve is cleaned, it is necessary to re-equip the special driving computer.

Because the throttle is squeezed by carbon deposit, the opening of the throttle will expand accordingly.

After cleaning, if it is not reset, the throttle opening will remain in the state before carbon deposition, and the air intake will increase, which will lead to unstable idle speed, too high speed and increased engine fuel consumption.

However, for the mechanical cable throttle, the negative battery can be disconnected after cleaning the throttle, and the driving computer will automatically reset the data in about 15 minutes to adjust the throttle opening according to the new driving habits, but it will reset itself after driving about 10 km.

Throttle cleaning procedure

② Remove the air filter box first, and then remove the hose connecting the throttle and the air filter element;

(3) Then unplug the throttle wire and sensor, and unscrew the fixed throttle bolt to complete the disassembly;
