Idle learn procedure.

[accentstencil]

Is this really necessary, that's 40 minutes of idling.

IDLE LEARN PROCEDURE
Whenever the PCM or the battery is disconnected or the PCM loses power, the PCM’s learned position of the IAC
valve pintle is lost, resulting in an unstable idle.
Perform the following procedure in order to return the IAC valve pintle to the correct position:
Automatic Transmission
1. Turn OFF the ignition.
2. Restore the PCM battery feed.
3. Turn OFF the A/C controls.
4. Set the park brake and block the drive wheels.
5. Start the engine.
6. Shift the transmission selector to D (drive).
7. Allow the engine to idle for 10 minutes.
8. Turn ON the A/C controls.
9. Allow the engine to idle for 10 minutes.
10. Shift the transmission selector to P (park).
11. Allow the engine to idle for 10 minutes.
12. Turn OFF the A/C controls.
13. Allow the engine to idle for 10 minutes.
14. Turn OFF the engine for 30 seconds.

I just turn on car and drive

10 seconds not minutes works just fine.

I might give it a give it a go as it might fix the shudder problem outlined in my other thread.
Seems like a pain going through that every time the battery gets disconnected.

Me too, but perhaps that's not good enough.

Stuttering can be a few things from throttle position sensor, spark plugs, ignition coils to spark plug leads if old, fuel pump and fuel filter
Even gaps in the gaskets on the manifold

Dont think learning procedure will help, as car learns from driving anyway.

Good luck

I too was skeptical but it seems to have worked, not a single shudder when stopping.
I suppose Holden know what needs to be done but they could have made it a little easier, maybe 5 minutes between each step instead of 10.

As a side note " THIS PROCEDURE IS FOR THE 5.7 LITRE V8".

Odd but happy to be corrected.

I used to do something similar to my Falcon, wasnt about stuttering though and just for battery disconnecting, was just procedure i followed for the Ford and was told the Commodore doesnt need similar

40 minutes... Bloody Hell, Well at least it worked and wasn't a waste of fuel.
It's bad enough watching the clock when doing it with a manual for 20 minutes.

IDLE RELEARN FOR MANUAL
All accessories off
Idle 10 mins with A/C on
Idle 10 mins with A/C off
Engine off for a minimum of 30 seconds before restarting

I have to agree 100% that it works.
I've had an issue a couple of times with mine since I've owned it where it wouldn't return to idle and it would hang at 1,000 - 1,100rpm.....revving it a couple of times didn't work either.
Doing the idle relearn procedure fixed it each time

Just to add:
Because I use a K&N Filter, the first time it started idling high I figured the MAF probably got oil on it's sensor wires and caused the issue.
Cleaning the MAF didn't fix the issue, did the idle relearn and it was all good again.

It needs to learn idle! ?
News to me.
Would have thought there would be a default reset. I bet no one does all that.
Useful if it solved your problem at least.
