hey, i think you are having a similar problem to my brother. my brother has a 240SX hatch (KA24E). his car starts at optimal air/fuel, then it slowly goes up to rich. while in idle, the car reaches its richest state, then while driving, the air/fuel bounces back and forth between lean and rich. we are going to clean out the throttlebody and replace the air filter to see if maybe that is doing it, but i think it may be something a little deeper...
