I've got a P0401 on my 1995. Had someone look at it and they suggested replacing the entire system essentially...the EGR valve, VSV, temp sensor. I checked it out today and noticed that there are a couple of open lines that have nothing connected to them. Upon comparing to other pictures, I found that there typically is a tube that runs there, but I don't have one. I've attached a picture if anyone can let me know if these two lines are supposed to be connected. If so, would that be the problem? Super noob here...thanks.
