ISC solenoid repair?

[Nike]

Looking at all the above, we can conclude: No classic push-pull relationship between RPM and ISC solenoid. ISC will be active only on the basis of external information and partially included short time after starting the engine. ISC will also be activated when the driver presses the accelerator pedal and the increasing speed, although I see no purpose ... Then the throttle already sufficiently open and open ISC plays no role.
Purpose of may be only a slight decrease in turnover release the gas pedal, wherein the air flow remains that the engine would not choked.

Maybe I'm wrong, but I think it works like this system.
