Mitsubishi Xpander Throttle Body Cleaning Malaysia
Throttle body carbon deposits are the most common cause of rough idle on Xpander at 60,000–80,000 km. Cleaning removes the carbon layer from the butterfly valve and housing. Always perform idle relearn (throttle position adaptation) after cleaning — skipping this causes rough idle immediately after the service. Malaysia's stop-start city traffic and short trips accelerate throttle body fouling.
