HI Derek.

There are a few possibilities that come to mind.
3K RPM is generally about the break-even point for when Turbo boost would kick in. There is a dump valve on the turbo system that opens up and vents the extra turbo pressure under high-rpm situations where the boost isn't needed - say high but steady speed on a freeway. If the dump valve system is malfunctioning, then that anticipated turbo run-up in power won't happen.

Revving fine when in neutral may not tell you much, other than that the engine can rev. The gating system will (or should) run differently under load - whether climbing a hill or accelerating, this is where you want the turbo boost to give you the extra power. THat's where the exhaust gate should stay shut, or mostly shut, to allow the turbo to force more air into the pistons.

You might want to check whether the APC (Automatic Performance Control) for the turbo has a separate fuse. (The name might be different on your model, I'm remembering from my 80s/90s era Saabs). If the fuse is blown, that could also lead to lame performance, especially as I'd imagine that the system would be built to fail or go to full open if the APC fails or loses power - that'd keep people from having run-away power that they can't manage.

Hoping this helps

SOURCE: saab 9000 cse turbo

Hi Steve,
I had a similar problem on a full pressure SAAB 9000. With me it only happened under hard acceleration, and it was caused by the Waste Gate Controller being sticky and over-boosting the engine to the point where the overpressure switch came into play - this cuts out the engine till the pressure drops to a safe level again - hence the sudden loss of power. On the full pressure turbo's you get a boost gauge so you can see it happening, but I don't think the LPT's have one fitted - so its probably a garage job - otherwise Saab9000.com will show you how to test it yourself.

Regards

Hugh

SOURCE: engine will not rev above 3000 rpm

Inadequate fuel pressure, change the fuel filter first, make sure the car sits for at least two hours before replacing the fuel filter because these fuel lines are under high pressure during the time of operation. The pressure usually decreases over time in the lines but wear safety glasses just the same, I would recomend depressurizing the fuel system first, buy a Haynes repair manual for detailed procedure to be safe. If problem persists go to Auto Zone and ask them to check for trouble codes these codes if present may instuct you in detail to replace the MAF sensor or give you a code that must be looked up to find the problem.
