Hope this is of some help to someone trying/planning to take on this task.
Recently purchased a 98' 93 2.3i for my wife to run around in (while we rebuild her classic beetle). Have to say I'm quite taken with it. The difference between my diesel company Astra and the Saab is fantastic!
Anywho, I digress.
The 93 was a bit of a chore to drive due to alarming 'snatching' when the throttle was applied or lifted off. The gear lever moved quite significantly in it's gaiter. If accelerating hard, there was a loud BANG as I lifted off to change gear. Finding gears was also a problem, and when slowing down from a cruise, it was very difficult to get out of 5th.
A bit of trawling the forums I suspected one of the mounts had failed. To check this do the following:
1: Handbrake on, chock the rear wheels front & back.
2: Pop the bonnet, get an assistant who can drive, or at least who can control a clutch.
3: While you look at the engine, get your assistant to select first, find the bite point, then feed in the clutch and some power. See if the engine moves.
4: Repeat in reverse.
With our 93 the engine only moved in reverse. It moved forward to a point, then suddenly leapt forward a good inch as more power was applied. Diagnosis. Rear gearbox mount.
