What is the high idle speed of KIA k2 after throttle cleaning?

This is because the throttle must be set after the throttle is washed. If it is not set, the idle speed will rise and fall. It is recommended to go to a 4S shop and let professionals decide.

In the intake process, impurities will accumulate at the throttle for a long time, and the carbon deposition will increase after a long time. When the throttle moves back and forth, it will be resisted. If this situation persists for a long time, the engine computer will adjust the position of the accelerator pedal. That is to say, the position of carbon deposition is taken as the body, which means that the throttle is not in place at all, but close to the position of carbon deposition.

After cleaning the intake valve of the vehicle, the flap still moves in the original formation, which means that it is not in place. The difference is that the carbon deposit has been cleaned.

Precautions:

1. Please use special cleaning agent for electronic throttle; If there is no special cleaning agent, use carburetor cleaning agent, first spray the cleaning agent on a clean soft cloth, and then wipe it repeatedly with a soft cloth to remove carbon deposit or sludge.

2. When cleaning the throttle valve, it is not necessary to disassemble it, but the sealing part of the inlet steam must be cleaned, and the idle motor must be disassembled for cleaning. Dismantling and cleaning nozzles have their own advantages and disadvantages. Generally speaking, the repair shop suggests that disassembly and cleaning are not needed to prevent other unnecessary waste, such as replacing the sealing ring or installing other gaskets after disassembly, or delaying the owner's time due to oil leakage during disassembly.

3. When cleaning the throttle valve, first remove the intake throat, expose the throttle valve, remove the negative electrode of the battery, turn off the ignition switch, straighten the throttle plate, spray a small amount of carburetor cleaner into the throttle valve, and carefully scrub it with polyester rag or high-spinning non-woven fabric. Deep in the throttle, you can clamp the rag and scrub it carefully where you can't reach it.
