Nissan Latio Throttle Body Cleaning Malaysia
Throttle body cleaning is one of the most impactful services on the Latio HR15DE at 20,000 km. Carbon deposits from blow-by gases reduce the throttle opening area, causing rough idle, low-speed hesitation, and occasional stalling. Cleaning method: spray-based cleaning without removal is effective for moderate buildup; full removal and chemical cleaning for heavy deposits. Always perform idle relearn/throttle relearn procedure after cleaning to reset the ECU's idle adaptation values.
