The fuel pressure regulator is a device that controls the amount of fuel that is delivered to the engine. If the fuel pressure regulator is faulty, it can cause the engine to run too lean or too rich. This can cause a number of problems, including:
- Engine misfires
- Stalling
- Hesitation
- Reduced fuel economy
- Check engine light
If you are experiencing any of these problems, it is important to have your car diagnosed by a qualified mechanic. They can determine if the fuel pressure regulator is the cause of the problem and replace it if necessary.
