Porsche 993 low idle software correction

The Porsche 993 with a VarioRam intake system can exhibit symptoms of low idle speed. The recommended idle speed should be around 870 RPM. Suppose the engine does not have mechanical problems such as air leaks or defective electronic components (idle control valve, defective ignition components, or fuel injection components). In that case, a software correction is needed to increase the idle speed to a comfortable and healthy level.
