87 Trans Am Starts but won't idle

I've got a problem I need some help with. I've got a 5.7L 87 Trans Am with TPI that will start and run as long as I keep my foot on the gas. As soon as I let off the gas she stalls. I've replaced the IAC and replaced vacuum lines. It seems like it's running rich as well.

Only code I'm getting is 12 ....

Any help would be welcome

Well it's fixed. I replaced the throttle position sensor, and the idle air control valve and sprayed the crap out of the throttle body with throttle body cleaner (lots of nasty stuff came out) and it fired right up and idle's smooth.
