Soppy Saab

If the MIL is lit, then chances are it in LOS mode. Now it should still present some boost over 2000rpm. If there was a severe problem, revs would be limited to around 3500rpm, which doesnt seem to be the case.

I would carry out a preliminary check of all intake hoses looking for splits and disconnections, check the turbo is free to spin, and that as far as you can see the wastegate is not stuck open.

Otherwise there is no option than to have the codes read to point you in the right direction.

You may have a blocked cat / exhaust, but I would a) expect very low rev pre-turbo performance to be fine, and b) it not to rev to the redline as it became more asphixiated as the turbo started to blow. Is still possible though.

Tim (remove obvious) ( snipped-for-privacy@NObtinternetSPAM.com) gurgled happily, sounding much like they were saying :

That's both the easiest to check and the most likely, I'd reckon.

It is just possible that you have a random glitch in the engine management system or sensors that it responds to. In addition to the suggestions of the other replies, I would try taking out the fuse for the ECU for 20 seconds or so. On my car, this resets it to default values.
