What Happens If the Throttle Body Isn't Cleaned for 100,000 Kilometers?

[LeMaximus]

If the throttle body isn't cleaned for 100,000 kilometers, carbon deposits will become severe, causing blockages that affect the engine's air intake. This can lead to issues such as rough idling, stalling, and unsteady acceleration with noticeable jerking. It is recommended to clean the throttle body every 20,000 kilometers. However, if the driving conditions are good and there are no symptoms like rough idling, cleaning it every 50,000 kilometers is also acceptable. There are two methods for cleaning the throttle body: one requires disassembly, while the other doesn't. If the throttle body isn't heavily soiled, it can be cleaned directly with a cleaning agent without removal. If it's heavily dirty, disassembling it for cleaning is more effective, though more time-consuming.
