I've got a strange problem!!!! After returning from vacation my 540 runs very rough and won't keep idle.Looking at the engine I found an open vacuum line.When plugging the line with my finger the car runs fine. Does anyone know what it is and what's supposed to be attatched to it? There are NO open lines I can see and I think someone took it out while I was away. Any help would be valuable!!! Thanks everyone
that part is in the shape of a "T" the bottom of the t connects to the black thing you're talking about. I'll get a pic from the side and post it so someone can narrow it down. Thanx a million for your help!!!! I'm getting an ulcer!!!
