What is the question, the idle speed or the knock sensor? The idle speed is not adjustable, it is computer controlled, if it has a stalling problem then the idle speed control valve is dirty.
The Knock sensor is just that, it senses what some people call spark knock, some pinging and others cylinder detonation, it sends a signal to the computer that the engine is knocking and the timing is then retarded until the knock stops, it can not completely stop knock but in most cases it controls it well as long as the engine is in good condition and the right grade of gas is used.

Testimonial: "i thought the idle was ecu controlled,but i see what your saying,ajust cable stop.ie allen screw with locknut to bring up revs.thanks"
Idle is factory set and cannot be adjusted, your best bet is checking for cracked hose pipework for air intake at idle,(not at problem under exceleration and driving) Any slight upset to the air /fuel ratio will be most prevelent at idle speeds.Check hoses where the meet metal flanges on manifold intakes and any sharp bends in ppipes.Good luck

P0505 is correct, but replacing the IAC won't help if the PCM cannot control and/or monitor the operation
you need to measure voltage at the IAC and/or the signal return to the PCM
