Hi Nathan,
I had this fault a few weeks ago; high idle of 1,100 rpm when first starting on a warm summer's day rising to 2,000 - 3,000 rpm as the engine reached normal operating temperature. The car could not be driven safely, as you've said.
To my surprise the idle air control stepper motor was the culprit. It's the cone on the end of the motor shaft which controls the amount of air by-passing the throttle butterfly.
By the way, you mentioned the procedure of resetting the throttle position by fully pressing the pedal a number of times. This only applies to the MEMS engine management fitted to the 1.8 engines. It is not a feature of the KV6.
