Hi everyone, I need some help with identifying some lines underneath my 2003 tj. I have p0455 and p0456 codes and I was inspecting what I believe to be vacuum lines to try and identify the cause of the codes. I found a cracked line underneath the car that traces back to the intake manifold. I did my best to circle the lines and take a couple of pictures to identify the affected area. Before I change out the line, I just want to make sure that it's actually a vacuum line. The car runs perfectly fine. Thanks
