MAP Sensor Failure?

Having problem with all four O2 sensors throwing codes, checked about everything, new computer, stock program, wiring all OK. Is it possible a bad MAP sensor ( one on the back of the intake manifold ) could cause this? Car runs better after the Check engine light comes on. After reseting codes car runs badly.
Please help, running out of things to check! TIA

Do you have access to a computer scanner of any kind? Anything is possible with electronics. I use a Snapon Tools scanner for OBDII on pre 96 vehicles that will tell me the values of all sensors in real time. It is trivial to diagnose a bad sensor with such a tool. Autotap works well with the new 96+ OBD systems.
