Default 81 idle help

My Vette (81) will not idle down after warm up. It idle's at around 1500 rpm's and will not idle down to the 800 rpm range it is supposed to be in. Car runs really good with no codes from the ECM. My shop manuel does not address this problem. Anyone have any suggestions?

Thanks
Trent81
