SR20DET Runs great till it warms up then gets rich and doesnt want to idle

Where should I start on this or has anyone else had the same problem with the SR20DET running fine when cool and then its like you hit a switch and all the sudden it runs rich and doesnt want to idle when warmed up. Could it be a MAF sensor??? O2 sensor??

Was your car running just fine when it was cold?? Mine is and when it stalls out when warmed up it is a pain to get started again, I gotta crank it over forever.
