A few weeks ago I posted about a overheating issue. I've been on vacation but finally getting back to looking things over. The Denver shop that fixed the coolant meltdown left the vacuum hoses looking in a bit of disarray. After getting car back from the shop I also noticed almost stalling at idle. I need new spark plugs and decided to do the work today. All this to say, I noticed a few vacuum lines that seem have been left out. See pictures below. Any advice on what needs to be done to correct this if it's a problem. Any diagrams available?
