I got a DTC that indicated that i have at least one oxygen sensor that is bad, so i replaced both oxygen sensors. i cleared the trouble codes and now the 'Check Engine' light stays off. however, after it reaches full operating temperature, the engine begins to refuse to idle. ..it just dies every time i come to a stop. i just need to know what items might be the (most likely) cause of the problem so i won't waste time getting it fixed.

Check the MAF sensor, idle air control valve/EGR and PCV valves
