Product Information
Full details
The Liqui Moly Pro Line Throttle Valve Cleaner is designed for gasoline engine owners seeking to improve engine performance and reliability by removing common deposits from the throttle valve system. Its primary benefit is restoring optimal airflow and engine responsiveness. A key consideration is its specific application to gasoline engines only and the potential need for diagnostic tool intervention post-use. This cleaner effectively loosens and removes oil, resin, and glue buildup, ensuring smooth operation of moving parts and increasing overall operational reliability.

Extended Product Information
FAQs
Is this cleaner suitable for diesel engines?
No, the Liqui Moly Pro Line Throttle Valve Cleaner is specifically designed for gasoline engines only.
Can I use this cleaner without removing the throttle body?
Yes, the product is designed for application without dismantling the throttle body. You spray it directly into the throttle valve area while the engine is running.
What should I do if my 'Check Engine' light comes on after using the cleaner?
If the check engine light appears, it may be due to a fault code related to the air flow meter or engine management system. You will likely need to use a diagnostic tool to clear the stored fault codes and potentially re-initialize the air flow meter.
How often should I use this throttle valve cleaner?
The frequency of use depends on driving conditions and engine condition. A general recommendation is to use it every 15,000 - 20,000 miles or when symptoms like rough idling or hesitant acceleration appear.
What are the main benefits of cleaning the throttle valve?
Cleaning the throttle valve helps restore proper airflow, leading to improved engine performance, smoother idling, better acceleration, increased fuel efficiency, and reduced emissions.
Can this cleaner damage my catalytic converter?
No, this product has been tested and is safe for use in vehicles equipped with catalytic converters.
What is the purpose of maintaining 2,000 RPM during application?
Maintaining a higher engine speed ensures the engine can process the introduced cleaner effectively and prevents stalling. It also helps to burn off residues after application.
Troubleshooting
Engine stalls or cannot maintain speed after application.
If the engine struggles to maintain speed with the intake pipe removed, disconnect the air flow meter plug (ignition off). After cleaning, use a diagnostic tool to clear fault codes from the engine control unit and re-learn the air flow meter if necessary.
Check Engine Light illuminates after use.
This is likely due to a stored fault code, especially if the air flow meter was affected. Use a compatible diagnostic device to read and clear the fault codes. The air flow meter may need to be re-calibrated or re-taught.
Minimal improvement in engine performance.
Stubborn or extremely thick deposits may require a second application of the cleaner. Ensure the spray was directed effectively at all soiled areas of the throttle valve.
Cleaner accidentally sprayed on painted surfaces or air flow meter.
Immediately wipe away any overspray with a clean cloth. If the air flow meter was significantly exposed, it may require professional cleaning or replacement. Painted surfaces may need touch-up if damage occurs.
Pros and Cons
Pros
- Significantly improves throttle response and engine smoothness.
- Cost-effective maintenance solution compared to component replacement.
- Easy to use with clear instructions for DIY application.
- Safe for use with catalytic converters.
- Helps in achieving better fuel efficiency.
Cons
- Strictly for gasoline engines; not suitable for diesel.
- May require a diagnostic tool to clear fault codes after use.
- Requires careful application to avoid contact with sensitive electronic components like the air flow meter.
- Stubborn deposits might require a second application.
Setup, Compatibility & Care
Compatibility: This cleaner is specifically formulated for use in gasoline engines only. Ensure your vehicle is powered by a gasoline engine before use. It has been tested for compatibility with catalytic converters.
Setup & Application:
- Ensure direct access to the throttle valve.
- Start the engine and maintain a minimum speed of 2,000 revolutions per minute.
- Spray the Throttle Valve Cleaner in 2-3 second intervals using the provided spray probe, targeting the entire throttle valve area.
- If the engine speed fluctuates significantly (over 1,000 rpm), shorten the spray intervals.
- Crucially, avoid spraying the cleaner onto the air flow meter or painted surfaces.
- After application, run the engine for approximately 20 seconds at a minimum of 2,000 rpm to burn off any residues.
Important Notes:
- If the engine cannot maintain speed or start with the intake pipe removed, disconnect the air flow meter plug with the ignition off. After cleaning, use a diagnostic device to delete stored faults and potentially re-teach the air flow meter.
- For heavily soiled throttle valves, a second application may be necessary.
Care: Store the cans in a cool, dry place away from direct sunlight and ignition sources. Ensure the cap is securely fastened after each use.
