Nissan Sylphy Throttle Body Cleaning Malaysia
Sylphy MRA8DE throttle body carbon accumulates from 20,000 km, primarily from crankcase ventilation gases (PCV system). Symptoms: rough idle, stumble or hesitation from cold, slight surge when cruising. Chemical spray cleaning without removal is a quick fix; full throttle body removal and manual cleaning is more thorough. After cleaning, always perform an idle relearn procedure to reset the ECU's idle adaptation. Malaysia's city stop-start driving accelerates deposit buildup.
