Mine used to do the same thing but a little higher both hot and cold. Vac leaks and misadjusted TPS where the causes. I removed emissions and rats nest and it got much better. But I couldn't get it to rest at 750 consistantly until I adjusted the TPS. Then the idle was better as well as driving in general. It really makes a big difference.
