Car will start up and die immediately after startup unless I give it gas and keep it over 2000 RPM's soon as I take off the gas it will die immediately what will cause this I already changed it IAC and the tab sensers. No luck with either one of them I also around a code on it and came up with code 81 and 82 on an older code reader

If this has not been modified like putting a carburetor on it check am 1 and am 2 solenoids for not working or a vacuum leak going to them. It can also be a bad ECM. There is no code 81.
