No problem, I just want to listen its sound. Did you ever execute idle learning procedure? If not then do it once, hopefully the IAC valve will adjust to it's ideal steps. Refer to the picture:
One more thing, it is a normal behavior of Daewoo ECM that once RPMs are raised above 1100 rpms via IAC valve, it readjust the rpms at complete stop. For AC system to work accurately, do not drive the car for 30 seconds after switching 'ON' AC so that ECM properly readjust the RPM according to the load. Once the ECM has done its settings, there should be no fluctuation in the engine RPMS.
BTW which sensor you are referring as "Trip" sensor? There is nothing like trip sensor in a Daewoo. If you are referring to the AC compressor tripping function, it is controlled by the ECM when extra load on engine is sensed by it.
