Yea i'm having the same problem car runs strong at rpms over 1,000 but wants to idle really low. Usually wants to die coming off high rpms...

02 will not affect idle. it is only controlled by the iacv. You need to find out whats causing the iacv not to regulate the idle. if it runs strong and sputters/bogs when you let the rpms drop rapidly, that meanss the iacv is doing something funky. whether its gunked up, not powered or malfunctioning that is the main controller of your idle
