Non IAC Idle Problem

Non IAC Idle Problem
I bought this car about a month ago and I am still trying to get it to run right. Currently the idle is really messed up. When it's just sitting in park it sounds like its idling rough, but once it's warmed up and you put it into reverse or drive the rpm's drop quick and it dies unless you add some gas. It also will do the same when slowing down to a stop. If the car is warmed up and I am sitting at a light, the rpm's are jumping up and down and dipping down lower than 500 sometimes and will die unless i creep forward, in which case the car lunges. It's really messed up. I tried cleaning my IAC, I tried replacing the IAC, I tried looking for any vac leaks, I tried resetting the computer by leaving the negative cable off, I thought tuning it would help, but it didn't really change anything (I have a sniper tuner, which is delta force now). I am lost as to what to do. I would really appreciate your guys experience. Thanks

Have you tried resetting the throttle stop screw? Read more about this here...
Are you using the Special Forces software? If so what version?

Also I saw that the o2 sensors wire was cut so I told the tuner that it was deleted.

Front or rear O2 sensors? The car will run rich as snot and generally like crap without the front sensors present and functional...
