Is the car is idling 650 +- 50 without the AC?

Ignition timing should be 15 +-5 during idle when in park or neutral.

Here is full procedure from AllData:

Throttle Valve Closed Position Learning

DESCRIPTION
Throttle Valve Closed Position Learning is an operation to learn the fully closed position of the throttle valve by monitoring the throttle position sensor output signal. It must be performed each time harness connector of electric throttle control actuator or ECM is disconnected.

OPERATION PROCEDURE
Make sure that accelerator pedal is fully released.
Turn ignition switch ON.
Turn ignition switch OFF and wait at least 10 seconds . Make sure that throttle valve moves during above 10 seconds by confirming the operating sound.

Accelerator Pedal Released Position Learning

DESCRIPTION
Accelerator Pedal Released Position Learning is an operation to learn the fully released position of the accelerator pedal by monitoring the accelerator pedal position sensor output signal. It must be performed each time harness connector of accelerator pedal position sensor or ECM is disconnected.

OPERATION PROCEDURE
Make sure that accelerator pedal is fully released.
Turn ignition switch ON and wait at least 2 seconds .
Turn ignition switch OFF and wait at least 10 seconds .
Turn ignition switch ON and wait at least 2 seconds .
Turn ignition switch OFF and wait at least 10 seconds .

Idle Air Volume Learning

DESCRIPTION
Idle Air Volume Learning is an operation to learn the idle air volume that keeps each engine within the specific range. It must be performed under any of the following conditions:
Each time electric throttle control actuator or ECM is replaced.
Idle speed or ignition timing is out of specification.
PREPARATION
Before performing Idle Air Volume Learning, make sure that all of the following conditions are satisfied.
Learning will be cancelled if any of the following conditions are missed for even a moment.
Battery voltage: More than 12.9 V (At idle)
Engine coolant temperature: 70 - 100 degrees C (158 - 212 degrees F)
Park/neutral position (PNP) switch: ON
Electric load switch: OFF (Air conditioner, headlamp, rear window defogger)
On vehicles equipped with daytime light systems, if the parking brake is applied before the engine is started, the headlamp will not be illuminated.

Steering wheel: Neutral (Straight-ahead position)
Vehicle speed: Stopped
Transmission: Warmed-up
For A/T models with CONSULT-II
Drive vehicle until "ATF TEMP SE 1" in "DATA MONITOR" mode of "A/T" system indicates less than 0.9 V .
For A/T models without CONSULT-II and M/T models
Drive vehicle for 10 minutes .
Without CONSULT-II

NOTE:
It is better to count the time accurately with a clock.
It is impossible to switch the diagnostic mode when an accelerator pedal position sensor circuit has a malfunction.
Perform EC-78, "Accelerator Pedal Released Position Learning". See: Powertrain Management\Computers and Control Systems\Accelerator Pedal Position Sensor\Testing and Inspection
Perform EC-79, "Throttle Valve Closed Position Learning". See: Powertrain Management\Computers and Control Systems\Testing and Inspection\Programming and Relearning\Throttle Valve Closed Position Learning
Start engine and warm it up to normal operating temperature.
Check that all items listed under the topic PREPARATION (previously mentioned) are in good order.
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 .
Repeat the following procedure quickly five times within 5 seconds .
Fully depress the accelerator pedal.
Fully release the accelerator pedal.
Wait 7 seconds , fully depress the accelerator pedal and keep it for approx. 20 seconds until the MIL stops blinking and turned ON.
Fully release the accelerator pedal within 3 seconds after the MIL turned ON.
Start engine and let it idle.


Wait 20 seconds .


Rev up the engine two or three times and make sure that idle speed and ignition timing are within the specifications.
If idle speed and ignition timing are not within the specification, Idle Air Volume Learning will not be carried out successfully. In this case, find the cause of the incident by referring to the DIAGNOSTIC PROCEDURE.

DIAGNOSTIC PROCEDURE
If Idle Air Volume Learning cannot be performed successfully, proceed as follows:
Check that throttle valve is fully closed.
Check PCV valve operation.
Check that downstream of throttle valve is free from air leakage.
When the above three items check out OK, engine component parts and their installation condition are questionable. Check and eliminate the cause of the incident. It is useful to perform EC-143, "TROUBLE DIAGNOSIS - SPECIFICATION VALUE". See: Powertrain Management\Computers and Control Systems\Testing and Inspection\Monitors, Trips, Drive Cycles and Readiness Codes\Specification (SP) Value
If any of the following conditions occur after the engine has started, eliminate the cause of the incident and perform Idle Air Volume Learning all over again:
Engine stalls.
Erroneous idle.
