Welcome to Saab Central, Kfes
We do need all of the details, without this, guesses are wildly out of control.
I am not certain that your ride even has a "limp home"....

What type of prob are you having?and like EW said ngs dont go into limp mode iirc.

I see, after visiting my local saab dealership, I was told that my Idle air control valve is bad and it has to be replaced, and the car is in Limp Home Mode. Starting in the morning is fine, but when shifting to (R) or (D) gear car is shacking like crazy and than shutting off. It runs much better after warming up for 10-15 min. But during driving it is hard to take off the stop light or stop sign, the car behaving weird.

Well if it is your iac valve i have one if you need.

Your car has no limp mode!

As hkyassi stated there is no limp mode, but if your car is still having probs then the iac valve wasnt the culprit.

my 96 900se has a "limp home" mode that causes it to be stuck in 3rd gear, but it has nothing to do with the throttle body. Limp home mode is caused by the transmission range switch, and it will also cause the "check gearbox" light to be on. The range switch can be disassembled and cleaned. Being stuck in 3rd makes for sluggish take-off, to say the least.

The later 9-5's had the throttle body limp home symptom. Don't know about 9-3's

He's talking about a different thing, he's talking about the throttle body. You're talking about a transmission protection mechanism; that mechanism triggers the check gearbox warning and the poster didn't mention any of that. The 9-3s have a lever on the throttle body to reset the limp mode. That is generally triggered by (but not limited to) a problem with the throttle body

Have you accidentally pressed the winter button? What sort of RPM are you seeing as you are having the slow movement from stop?
