you should get the codes read for the engine, this could be a LOT of different things.
what stands out to me is once its warm it seems OK. I would take a guess at either an O2 or mass airflow sensor or a catalytic converter problem. Until you get the check engine code read by someone its pretty hard to pinpoint your problem. I would start there, if you wait for a long time its possible you may do more expensive damage to the engine.
