Hi could be that the TPS needs adjusting....had the same problem on mine...high idle ..approx 2000 rpm cold and warm...(I pulled the plug off teh ISCV and the idle was ok ..I only needed to hold the throttle a bit open when cold...but when warm it was fine) ..... first I thourght it was the ISCV and I cleaned it...even tried a new one..but no change. then I checked the TPS and somehow it had moved (still I dont understand how that could happen, as the screws where not loose)...I adjusted the TPS...and voila...all was ok
