Just bought a 97 Contour

60,000 Miles, 2.0 ltr engine, automatic.

I have a couple of problems to fix currently. At idle when in gear the engine will sit at about 600rpm, causing the steering wheel and dash to vibrate. Also the engine temp gauge does not work.

The dash and B pillar are a little beat up on the interior so I want to get new parts and fix it.

Any links or tips you have are much appreciated.
