intermittent high engine idle

Engine

Vehicle Information: Model: 911 carerra; Year: 1988; Body Type: Targa; Engine (type, size, modifications): stantard 3.2; Total Mileage: 46,000;

i am experiencing high engine idle on an intermittent basis. warmed up engine, usually after 20 minutes of driving....local and/or hwy. when coming to a stop into neutral, the idle sometimes kicks up to 1500, 2000, or even 3000 rpm. happens also sometimes when cruising along in gear. i notice that when i take my foot off accelerator, car seems to be in cruise control mode (never touch it or use it!) Idle will kick back down to norm (900 - 1100 rpm) when i give the accelerator a quick push and release.had a new bosch idle contol valve installed, but no change. any thoughts?
