And this I can tell you now is not because of any lack of compression, though because of the high idle I wouldn't be surprised if that caused the exhaust valves burning out.
Also high idle on your car could be caused by a failed intake manifold gasket by the cylinder 1 intake runner, To verify if this is the problem you will need a can of carb cleaner and spray just below the power steering pump where the intake manifold meets the cylinderhead, If idle changes or the engine stumbles the gasket is leaking and needs to be replaced.
