If you have a stock ECU and no piggyback fuel controllers, you'll be limited to idle control. It sounds like that's what you're looking for anyway. Stock RPM specs are in the FSM (factory service manual), and will be 750 +- 50 RPM. Idle AFRs are fine at 13.0. When cold, you'll notice them start lower (11s or 12s), then move up as the engine warms.
