Many causes such as:
1-bad O2 sensor
2-air leak
3-too many mods
4-improperly adjusted TB
5-bad or improperly adjusted TPS
6-improper fuel pressure
but since this problem occurs way too much even with stock engines
7-lousy Mazda idle control logic in for the ECU is the main reason.
If you have a PFC and DL and convert to manual idle control, the problem goes away.

don't race, don't need to
If you have the lights on (or any electrical load) and are in neutral and shift into first or second and have big idle fluctuations that go a way when you put it back in neutral, look to your clutch switch, the one on top of the clutch pedal that adjusts the pedal height. Replace it, mon
