What is the throttle idle data for the MG6?
2 Answers
The throttle idle data for the MG6 is approximately 1200 RPM after ignition. Throttle cleaning method: Cleaning the throttle: The throttle is essentially an air intake regulator. Although the intake air is filtered by the air filter, fine dust can still pass through the throttle. Additionally, there is an exhaust gas recirculation pipe connected to the valve cover in front of the throttle, where oil vapor and dust can mix to form sludge that easily accumulates on the back of the throttle. Excessive sludge can enter the combustion chamber with the intake air and also affect the throttle's sealing and flipping sensitivity, leading to poor idle and sluggish acceleration. Cleaning interval: This can be determined based on the air quality of the vehicle's operating location and the quality of the engine oil used. For DIY cleaning, it is recommended to clean every 20,000 to 30,000 kilometers depending on usage. If you cannot clean it yourself, you can take it to a repair shop, but the interval can be appropriately extended. Cleaning materials: Either canned pressurized specialized throttle cleaner or carburetor cleaner can be used, both of which are inexpensive. Disassembly cleaning: Repair shops often clean the throttle without disassembly by revving the engine at high throttle. In this method, the cleaner is sucked into the combustion chamber and mixed with fuel for combustion. When the cleaner encounters high temperatures, it can form some impurities and gum, which enter the catalytic converter, severely polluting it.
I frequently handle maintenance for the MG6, and the throttle idle opening really depends on the specific model and engine condition. For the 1.5T version, the normal value should be between 2.5° and 4°, with new cars typically maintaining around 3°. The key is to use an OBD scanner to check the data after the engine is warmed up—cold starts will show falsely high readings. If the reading exceeds 5°, that's a bad sign; it usually means the throttle valve plate is stuck with black carbon deposits, especially common in older cars frequently stuck in city traffic. After cleaning the throttle body, remember to reset it, or you'll end up with erratic idle speeds that fluctuate comically. I recommend using carburetor cleaner on the throttle plate every 20,000 km to avoid vibration issues caused by excessive opening.
