Perform the idle learn procedure whenever any of the following have been done.
-reset, replace, unplug, or reprogram ECM/PCM
-disconnect or replace battery
-do engine work that requires R&R of the intake manifold or the throttle body
To allow the ECM/PCM adaptive idle speed system to learn and adjust the engine idle speed here's what you do.
1. make sure all electrical items (A/C, radio unit, defogger, lights, etc.) are turned off, then start the engine.
2. let the engine reach its normal operating temperature (the cooling fans cycle twice; the coolant temperature is about 194 degrees F).
3. let the engine idle for atleast 5 minutes with the throttle fully closed and with all electrical items off.
4. if the cooling cans cycle, add the cycle time to the 5 minute adaptive learn time.
