I also had the shakes at about 2000 RPM in the lower gears. After checking the EGR system (which I believe starts functioning at around 2000 RPM), I pretty much gave up and resigned myself to mentioning it to my garage next time the beast is in. After getting a vague hint about fuelling problems causing the shakes (I've had the front end pretty much completely replaced in stages now, from the inner drivers to the ball joints; tyres as well) and putting that together with the fuel pump starting to make noises, I was very pleased to find that bypassing the fuel over-pressure switch has fixed both. I'd have no idea what to do otherwise. Am I on the right lines here (Dave/Grunff), or have I been a blessed recipient of coincidence? Jason - if it's a turbo, it's worth a try. You did hint that money is tight, so for the price of a 4mm hose joiner and half an hours work, I'd say go for it. Good luck pal, Paul 1989 900 Turbo S http://saab.go.dyndns.org/
