I know I am several years late to this thread, but here are the steps for a Nissan Altima 2004 idle timing Learning:

1) Turn ignition switch “OFF” and wait at least 10 seconds. Confirm that accelerator pedal is fully released, turn ignition switch “ON” and wait 3 seconds.

2) Repeat the following procedure quickly five times within 5 seconds.
Fully depress the accelerator pedal. Fully release the accelerator pedal.

3) Wait 7 seconds.

4) Fully depress the accelerator pedal and keep it for approx. 15+ seconds until the MIL stops blinking and turns ON.

5) Fully release the accelerator pedal within 3 seconds after the MIL is ON. Start engine and let it idle for about 20 seconds. It is learning correct idle settings. RPM at "P-parking" or "N-neutral" should be within the interval [650rpm to 750rpm] and ignition timing should be within the interval [+15 to -15].

Hope this helps, car should be much smoother after this.
