Cause of engine over run - Engine mount or Flywheel?

[jodyburton]

What's the more likely cause of my engine over run and wobble/shake when I switch the ignition off?

When the car is ticking over and the A/C is on you can feel the car vibrating sightly.

Also off the subject I need a new microswitch for the boot, Dealer want £25 for the part, can't find them anywhere else. Anyone know where I can get one cheaper or are they dealer part only?

Thanks

Ebay search for "307 breaking" and find someone local breaking one near you.

Another thing is when I start the car it gives an almighty shake and a slight belt squeal when ticking over (timing belt has been replaced). Would the new flywheel tighten up the running of the car?
