You'll find it on the fuel rail where the injectors are, it will have a vacuum hose going to it, but I don't think that's your problem, pressure regulators almost never fail, have you performed a vacuum test on it? Start out by replacing the fuel filter then check the fuel pressure

Would the fuel pressure regulator make my car not run right. And it run to high

Yes.... No.... if the vehicle is idling too high it maybe a vacuum leak, check all of hoses make sure they are in good condition, without more information I can not help you. Please fill out the following form:
