Some Guidance for an E28 M5 would be appreciated! (archive)

I a fit of motor madness I impulsively purchased an E28 M5 last week. This
past weekend I started taking things apart and ran into a simple problem I
hope the collective brain has a simple solution for. In driving the car over
the past week, I have noticed several other things that I am curious
about.....

1. What kind of socket do I need to get the spark plugs out. It looks like a
17mm to me, however I do not have one deep enough to remove the SPlug.
Suggestions?

2. The car idles at ~650 rpm and seems to hunt a fair amount. Any thoughts?

3. Is there a service manual for this car available (esp. engine info?)?

4. Runs flat between 1000-2500 rpm with some hesitation. Again, any others
who have solved this? After 2500 it goes like a scalded cat although I still
suspect it is not running at its full potential.

5. The rear of the car shudders slightly upon takeoff from a dead stop.
Again, anyone experienced with this sensation?

Misc Facts; The engine has a chip (Bav Auto I believe, need to open the brain
to confirm) and a K&N. Based on the maintenance records, I suspect the fuel
filter has not been changed recently. One of my first maintenance tasks. Plug
are ?? old. New rotor, dist cap ~ 16K ago. Plug wires appear original.

Thanks for the input.
