idle on your car either clean the Idle control valve or replace or check for airleaks- manifold gasket, airbox, airbox piping, brake bias pipe.

earth - check the internal earths i'd run a new one from the metal part of the dash to the body to try and rule it out as the dash. then go into the engine bay and start running them there.
