Does Subaru car need computer matching to clean the throttle?

Any car is recommended to do computer matching after cleaning the throttle.

Because the opening and closing angle is actually very small, about 5. A little more or less will directly affect the calculation of combustion by computer.

So as long as you move the throttle and do some computer matching, let the computer know what the latest intake situation is.

Only in this way can we give full play to the advantages of computers.
