bad iac?

[hamburglar]

My SHO will start fine. But when I'm at idle and give the car any gas the throttle response is not good and the tach dips to ~500 rpms and the car almost dies. Then the RPMs will kick back up and once the car is moving their is no problem.
MY o2 sensors threw codes, could it be the o2 sensors or IAC?

i would pull it off and give it a good cleaning, also try unplugging the maf and see if it is any better

your description is not of an 02 sensor problem. very good chance it is a sticky iac.
