Mitsubishi Eclipse Cross Throttle Body Cleaning Malaysia
The throttle body on the Eclipse Cross 4B40 engine can accumulate carbon deposits over time, leading to rough idle, hesitation, and inconsistent throttle response. Cleaning is recommended at around 60,000 km intervals or whenever idle quality deteriorates. Unlike port-injection engines, the direct injection 4B40 does not benefit from fuel system cleaners passing through the intake, so physical throttle cleaning is more important. An electronic throttle relearn procedure is often required after cleaning.
Eclipse Cross Throttle Body Cleaning
- Clean throttle body every 40,000 km — direct injection means oil vapour from PCV can deposit carbon on throttle butterfly
- Turbo blow-off valve and intercooler: inspect connections for carbon oiling at 60,000 km
- Rough idle, hesitation on initial acceleration, and stalling at junctions indicate throttle body needs cleaning
