Revving the engine to around 3,000 rpm when stationary (no need to
sustain it) will probably do the trick.

This was covered less than a month ago.

For these Magnas removing the battery for any extended period (more than
10mins) can reset the computer. Idle speed is controlled by a idle stepper
motor and it takes some time for the computer to figure out how much is
enough to maintain a steady idle.

No option here, just drive the car and watch it every time you lift off the
acclerator and brake. Engine will most likely die so be quick to get it into
neutral and start it so you can retain your power steering and brakes.

DO NOT force it to idle by holding the throttle open while on the brakes (in
gear)!

It's a pain in the neck I know. I dealt with the same thing when we bought
the magna as a gift for someone. Fitted a decent radio and in doing so lost
the idle. Took me close to a week of driving to/from work to get it sorted.

You need a mix of driving that involves going back to idle regularly,
freeway driving won't help sort out the idle speed.

Would have to be!
A rusty ZG would be 150% on a magna!
Unless, it was powered by Brigs and Stratton.
No blue smoke, no rattling chains and nitro compatable :-)

ECU will cover up faults by adjusting around them.
Most common fault is old sparkplugs, or dodgy leads. ECU has reset and now needs to readjust for the fault.

Do you know when the plugs were changed?

When the engine has no other faults, the procedure after warming up is to let the engine idle for 10 minutes.
If you can't don't wan t to fix the fault..whatever it may be, the method is to open the throttle just enough to get a stable idle, then let it idle for he 10 minutes.
You'll have to put up with a fast idle for the next 30 minutes min until the thing then decides that it can adjust back down again.

This Magna has been running very well with only routine maintenace,
including a previous battery without any problems.

I hear you can drive almost any car you like on a Playstation.

Maybe next time you could jumper another battery onto the battery clamps
while you change the battery.

The 3 litre 12 valve Magnas won't respond to this sort of treatment,
alas. The IAC valve is *not*, as it is for most cars, driven right to
the end of it's travel at engine startup or indeed, under *any*
circumstances, except when the dealer plugs in the diagnostic tool and
tells the ECU to do it. Unfortunately, only MrBishi dealers have the
appropriate tool - as you can imagine, having a captive market, it
ain't cheap to get done.

That said, you can dodge it to some degree by screwing up the base
idle (idle stop screw on throttle body), but make sure you re-adjust
the TPS afterwards (it'll be even worse if you don't!). Of course,
that may be the problem anyway (badly adjusted TPS), but it sounds
like the ECU has simply forgotten where the IAC stepper motor is
(always does when you disconnect the battery)
