Does the JAC Refine M3 throttle need to be matched?
2 Answers
After cleaning the throttle of the JAC Refine M3, it needs to be rematched. If not reset after cleaning, the throttle opening will remain in the pre-carbon-deposit state, increasing the air intake, which can lead to unstable idling and excessively high engine speed. The method for matching the JAC Refine M3 throttle is as follows: 1. First, turn the key to the power supply position, but do not start the car; it should remain in the off state. 2. After leaving it for about 10 seconds, quickly press the accelerator pedal all the way down, making sure to press it down quickly and completely, and hold it for 15 seconds before quickly releasing it. 3. Finally, turn off the ignition, remove the key, and leave it for about 15 seconds.
As an experienced car enthusiast who often tinkers with vehicles, I must say that for a car like the JAC Refine M3, it's essential to perform a throttle matching after cleaning or replacing the throttle body. Throttle matching allows the car's ECU to recalibrate the opening and closing positions of the throttle body. Since the electronic system automatically memorizes the original settings, any changes can confuse the ECU, leading to erratic idling, unstable starts, or sudden increases in fuel consumption. I've personally seen many Refine owners overlook this at repair shops, resulting in their cars running as if they were drunk. It's advisable to have a professional mechanic handle it with a diagnostic tool—it's hassle-free and safe. After all, the matching process is straightforward, doesn’t cost much, but can prevent more serious engine issues. Also, don’t forget to pay attention to throttle cleanliness during regular maintenance to avoid frequent problems, ensuring a smoother drive.
