Car is good other than egr valve code 33 and 41. I found that the line from my charcoal canister to upper manifold is horrible. I have a new line on the way. On the passenger side towards the back there is a vacuum line with a blue and black tip that I cannot find where it connects to. Also my red vacuum line splits into a double line and I cannot figure out where that line that is connected to nothing goes to. Any help or knowledge is greatly appreciated. Thanks in advance.
