The fuel pressure regulator controls the amount of fuel that is delivered to the engine. If the fuel pressure regulator is not working properly, it can cause too much or too little fuel to be delivered to the engine. This can cause the engine to misfire.
Other symptoms of a bad fuel pressure regulator include:
- Engine stalling or hesitating
- Rough idle
- Check engine light illumination
If you are experiencing any of these symptoms, it is important to have your car checked by a mechanic to determine if the fuel pressure regulator is the cause.
