Hi all I had recently finished a repair of both head gaskets on my 91 thunderbird SC and after it was all said and done she starts no prob but doesn't want to stay running. She drops to really low RPMs and eventually stalls out. I was told this could be due to a vacuum leak by several people on here and another off site. I have checked the lines(those that I think are vacuum lines) and I don't seem to find anything out of place. I was wondering if someone may be able to point out the locations of the lines so I can recheck them a little more thoroughly. I thought that it may have been old fluids but it seems I was wrong. I have a attached a few pics of my engine in case someone can point them out from the pics alone. If you need a better pic tell me what you need to see and I will get it. I can't seem to find any diagrams of the vacuum lines that make a lot of sense to me. Thanks in advance. Also I would love any other suggestions as well, thanks again.
