Answer
Hi Nick:

You got me on the gringing noise It can be just about anything. But as for the hard start after sitting and running rough. My first guess wouls be a fuel delivery issue. either you have fuel injectors that are leaking when the engine is shut off and the fuel is leaking past the injectors into the engine and making a hard start or the fuel pressure is bleeding off back into the tank and you are getting a vapor lock in the fuel system making it hard to start. I would first look at the fuel system on this car. Good luck :)
