First, create direct access to the throttle valve by removing the air filter and start the engine to start cleaning.

If the engine cannot maintain speed with intake pipe removed or cannot be started, disconnect the plug from the air flow meter with the ignition switched off. In this case, the fault code must be deleted from the ECU after cleaning using a suitable diagnostic device and the air flow meter must be taught in again if necessary.

Then, spray this product across the entire area of the throttle valve while maintaining engine speed at around 2,000 RPM using the spray hose. If a speed fluctuates more than 1,000 RPM during application, shorten the spray intervals.

After use, allow the engine to run for about 20 seconds at min. 2,000 revolutions in order to burn any residues remaining in the intake system.

In the case of stubborn deposits on the throttle valve area, in the intake manifold or on the intake valves, we recommend to repeat the cleaning process with a second can of this product.

No. This product cleans the dirt on the throttle valve area through strong stream of sprays and dissolving the dirt, then removed from the engine through the exhaust during combustion. The content also evaporates without leaving any residues on the intake area.

This product may attack certain plastic or rubber parts sensitive to solvents. Please make sure not to spray this product on the air flow meter or painted parts.
