Welcome aboard Matt!
These problems you've got, first DON'T TOUCH THE THROTTLE STOP SCREW!!!
Second, which cables do you mean - the electrical cables or the Bowden cables for the kickdown, throttle and (if fitted) cruise control?
When it stalls, i'm guessing sometimes you'll be coasting to a stop just before it stalls? If so, keep an eye on the rev counter, if it drops like a stone and you still know the engine is turning, it points to the CPS - Crankshaft Position Sensor.
If the rev counter is still above zero, even if jumping about like a frog on a pogo-stick, the chances are the AICV (Air Idle Control Valve) and PCV system are filthy. You'll need some carb and air intake cleaner spray to solve this.
First you need to narrow the field a bit so it's in one area or the other - any other clues you spot along the way would be useful too!
It could also be down to a whole host of other things - those are the most common causes, need more clues first!
As for the fuel gauge - welcome to 7/9xx ownership!
Sometimes you get one that never fails, others will work when they feel like it and others just won't work at all. A good place to start would be the instrument pack, remove it and the multiplugs from behind with the exception of a single wire for the rev counter, the others can only go back where they came from and the way round they are meant to be.
Clean the copper tracks on the PCB where it folds round the housing to make the male connector for the plugs to fit on - use a piece of fine emery cloth gently.
Clean the contact "fingers" in the plugs the same way and using something thin and strong like a small Allen key, pull the curve out a bit so the fingers are more bowed - it's a tedious job but can work wonders. While you have the instruments out, replace any duff bulbs in it and if you're considering changing the bulbs for LEDs on the illumination, now would be a good time.
That may restore your fuel gauge operation - also check the mounting screws that hold the fuel gauge into the pod, they are accessible on the back of the instrument pod - loose screws will prevent good contact as they are also the gauge electrical connections.
The tracking may well be spot on but the camber could be out - Volvo did a modified suspension mount to correct this - it may also be someone has fitted an older set of front struts to it in the wrong position, altering the camber or the rear springs may be weak or lowered again, causing camber problems on the front.
Or it could simple be that it's toeing in too much!
Could be the spaceship bushes have worn out, the tracking was set correctly while they were worn and they've since been replaced - so many possibilities here! On the good side, it is self-centring very well and that's a positive sign. You probably notice it more as this is your first RWD Volvo with power steering, it's not so noticeable on the 3xx even with manual steering and the 440 is FWD with very little self-centring feel.
As for the parcel shelves, i think so but i'm not sure. Buy a cheap one, if it doesn't fit, ebay it again and maybe make a profit, if it does, you've got a cheap one!
