Do you need a special computer to adjust the idle speed after cleaning the throttle?

For Dongfeng Nissan Tiida or Nissan models sold after 2005, after cleaning the throttle or fuel nozzle, the operating factors in the maintenance process need to be matched by computer to modify the computer idle program to ensure the standard idle value and good fuel economy. In addition, combined with Nissan computer control program, it is impossible to cut off the battery and match the basic idle speed value. At this time, it can be operated manually, but it requires a certain degree of professionalism, which is difficult for non-professional technicians to complete. So I suggest you go to the repair shop for computer matching, which won't take long.
