Resolved Bad ECU or Not?

Hey guys, this has been my problem since day one, bought the car cranked it up and it ran fine until it warmed up, then it started sputtering and runnig rich, now, i tryed another stock mas and it didn't help so i decided to go ahead and start replacing things, the car was stock before i started now it has been about a month and a half and i have all my mods back on the car (see mod list) and once again, i can go out get in the car crank it up and it acts fine, i can drive it down the road (runs like a bat out of hell) but as soon as it warms up it goes crazy, sputtering, stalling and running extremely rich, (note: i also put a new o2 sensor in it as well) now i know that the computer runs in closed loop until it warms up and goes into open loop, it sounds like the car starts acting up as soon as it goes into open loop, so my main question is "is it possible that the computer is messed up in the open loop mode?" i have got another computer that i am going to install tonight but i was hopeing to get some input on the matter before then (notice the mod list i have a gm mas and a mas translator now) no matter what adjustments that i do it still acts the same PLEASE HELP!!!!!!! thanx guys.

it is definatly your computer.my car did the same thing.it took me forever to figure out what was wrong with it i even went as far as replacing my head gasket.but drive your car till it warms up and starts acting funny then pull your ecu out and take it apart and see if it smells funny like its burnt.and look for burn spots.if you do,its your ecu.mine was the same way on my 92 talon n/t....hope that helps.
