How to judge that the throttle is dirty?

The throttle valve of the vehicle is the place where the engine system sucks air, especially the throat, which will inevitably produce dirty things such as carbon deposition. So how do you judge that the throttle of the vehicle is dirty? The idle speed of the vehicle is a little wobbly, especially when the ignition is just started, the engine jitter is obvious, indicating that the throttle is a little dirty and I can feel it myself.

If you feel weak in acceleration when driving, it is not as smooth and fast as before, indicating that the throttle may be dirty. Of course, it is not necessarily that the throttle is dirty, but it may also be that there is something wrong with the oil circuit.

If you feel that the fuel consumption increases obviously when driving, you can eliminate the problems such as overloading the vehicle and driving at a low speed for a long time. It may be that the throttle is dirty.

Another way is to check the throttle when doing routine maintenance for the car, that is, open the throttle inlet and check it carefully. This method is relatively accurate.

When cleaning the throttle, it is not necessary to disassemble it, but the sealed part of the air inlet must be cleaned, and the idle motor must be disassembled for cleaning. Nozzle borrowing cleaning and disassembly-free cleaning have their own advantages and disadvantages. Generally speaking, the maintenance station suggests no disassembly and cleaning to prevent other unnecessary waste. Note that most cars are electronic throttles now. The accelerator should be reset after cleaning, otherwise the car will shake badly. (Photo/Text/Photo: Chen Yalan) @20 19
