My wagon turns off with the key without hesitation, the shifts are smooth, brakes good, locks don't work but I have to investigate that (found a golf tee in a line under the hood), so I figure I've got a pretty good vacuum system. Today the car wouldn't shut off and the shifts were really jerky. I figured I must have knocked a line loose while poking around under the hood while changing a headlight. Sure enough, one of the lines at the 4-way connector near the brake booster had come loose. I slipped in back in the 4-way and the car was back to normal. The thing that surprised me was how easily it can slip out again. Can I firm up this connection with something? I don't want to glue it in case I ever need to disconnect it again. Anybody got any suggestions?

Also, the line with the golf tee looks like it should connect with a line going into the fire wall...maybe the reason the locks don't work. And there's a purple line with a yellow stipe (i think) that comes from that area around the front of the engine bay and ends up on the passenger side of the valve cover by the air cleaner area, and its plugged with a screw. Anyone know what that's for? I can provide more info tomorrow if needed. But the car seems to work fine so I'm content without messing with it. Just curious I guess...
Appreciate the help,
-Geoff
