Question about 2001 Saab 9-3

1 Answer

I have a 1999 Saab 9-3, 2.0L. It is not able to keep a steady rpm. It will idle fine then almost die, then it revs quite high, and repeats all over. I have had new plugs put in, cleaned direct ignition cassette (ordered new one, just not here yet.), two new Bosch universal o2 sensors, and had mechanics run all diagnostics. We still can't get it running smoothly. I will say, after the sputtering is done when excellerating, it flies! And ideas out there? Thanks much! -Mark marksbluedogs@earthlink.net

My saab 95 1.9 tid revs fine in neutral when put in drive and pull of there's no power won't go above 3000 ram any ideas


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

I have 1999 Volvo C70 2.3 Turbo and it won't rev past 4k rpm. It idles fine,but stumbles and hesitates when the pedal is pressed. The CEL is on and the codes are for a cylinder misfire and an oxygen sensor...


4000 rpm is pretty high..it may have a fuel cut off for extremely high operation to prevent blowing it up..why so high?? most run between 2200-3000rpm..not 4000...

Starts just fine but dies at idle. will keep running when stepp[ng on gas pedal


if the car runs fine at high revs, I suggest just turning the idle revs up 150ish, it could be a block cat converter, or restricted airflow making it die. but quick fix turn revs up 150rpm will do no harm and if it dies at higher revs, take it 2 the garage to see if they can find the thing.

Have 1999 cavilleir does it have a rpm protecter


Yes, the PCM for your vehicle's engine has a rev/speed limit seeting programmed into it. Most stock, non high performance/police package vehicles usually won't go above a top speed of 97MPH. if you were to rev your engine while it was in park or neutral, once the engine reaches the cut out rpm limit preset in the PCM, it will cause the engine to cut back, then it will rev up until it hits the preset limit, then cut back, and it keep repeating that pattern. It may sound as though you have a high rev ignition failure that sounds like waaa, waaa, waaa, waaa, but that indicates the PCM is doing its job.

Won't start, engine wont rev above 2000rpm


Have the alternator tested. You are providing a low charge to the battery when you jump it and when taking it above 2K RPM requires more amperage resulting in the engine dying and the rough idle

Your car has traction control and is currently in limp home mode. you will not be able to fix this yourself as most shops are unable to fix these issues. However the most common problem is the safety valve located on the firewall passenger side.
