I having an issue with a P0174 code. It is intermittent in nature. I have located what I believe the problem is. It is a vacuum leak on the Bank 2 fuel rail.
It is coming from this sensor pictured below. What is this sensor and do I need to replace it? Can I just replace O rings or tighten it? Thank you.
