How to match the throttle of Jetta?

1. Turn off the ignition switch and wait at least 10 second. 2. Make sure that the accelerator pedal is completely released, turn the ignition switch to the on position and wait for 3 seconds. Repeat the following operations five times in 3.5 seconds. Fully depress the accelerator pedal. Loosen the accelerator pedal completely. 4. Wait for 7 seconds, fully press the accelerator pedal, and keep this state for about 20 seconds until the MIL stops flashing and starts to light up. 5. Fully release the accelerator pedal within 3 seconds after the 5.MIL light is turned on. 6. Start the engine and let it idle for a period of time. 7. Idle for more than 20 seconds; 8. Run the engine at high speed for two or three times to ensure that the idle speed and ignition timing meet the requirements. You'd better use a stopwatch for this time-critical program, otherwise the lights won't come out. If the throttle is not very dirty, don't match it without turning on the ignition switch during cleaning. If the idle speed is abnormal after cleaning, it is necessary to match the idle speed, because the ignition timing and idle speed value have exceeded the standard range. If the ignition switch is turned on or the plug of the throttle valve is unplugged during cleaning, idle matching is also needed. 43 1、04-060/ 10-00 @20 19
