OK two questions: I'm getting a code 34 for EVP voltage above closed limit. The check engine light will come on when the car's just warming up and when I give it gas. when I let off, the light goes away. This only happens when its just warming up and sometimes when I'm cruising on the highway. How do I check my EVP and what affect does this have on performance?

Second question. I just bought the car and there's a really loud beeping coming from behind the dash around the stereo area. It goes on for about thirty seconds when I turn the car on and it will come on for no reason when I'm driving too once in a while. Do Mustangs come with warning tones or something or is this just something to do with the last owner's stereo system. I've loked behind there and I can't find anything that's not supposed to be there.

Sorry this is a bit long.

Thanks in advance.
