Car wont start without

I have 5.3 with ls1 intake and the car wont start without pressing the accelerator and as soon as let off the car turns off. I have checked for vacuum leaks. the plugs are black as can be. i am running a maf sensor. we did notice that the o2 sensors dont seem to be working right with a scanner. i did buy them from the dealership. they are new. the computer is not throwing any codes.

Can you monitor the idle air control valve? Sound to me like its bad.

we replaced it and started right up stayed on for 1 or 2 min and we turned the car off then tried to start it and i did the same thing. we are thinking it has something to do with the computer
