Mitsubishi ASX Throttle Body Cleaning Malaysia
Throttle body cleaning is recommended for the Mitsubishi ASX at 60,000 km intervals. Carbon and varnish deposits accumulate on the throttle plate and bore over time, reducing airflow accuracy and causing symptoms such as rough idle, hesitation, and slightly elevated idle speed. The cleaning procedure involves using a throttle body cleaner spray with the engine off and carefully wiping the bore and plate. Some workshops perform the cleaning with a driveability check to confirm idle stabilisation after the procedure.
ASX Throttle Body Cleaning
- Clean throttle body every 40,000 km to restore idle quality and throttle response
- Carbon deposits on the butterfly valve cause hunting idle, rough start, and hesitation on tip-in
- Use throttle body cleaner spray; do not use carburetor cleaner as it damages rubber seals
