when i pop my tranny out of gear the idle will drop to about 500 sometime 400 rpm, recently cleaned up my K&N airfilter and had an oil change, does this mean that i need to clean up my idle air control valve or is it something else…whether the car is warm or cold it does this periodically not all the time any ideas? ---

ah yes, idle-dipping-disease. Both my S13 did it. one still does. I’ve read a bit re: this, the one solution I remember was that (someone else) cleaned alll they’re electrical connections/plugs and re-attacthed them (in the engine bay) ??? ---
