[QUOTE="Rainmaker, post: 162455, member: 3912"] I was looking under the hood today of recently purchased 7.3 L Excursion. I noticed somebody took a nail, flattened end, plugged up a vacuum line behind the passenger battery on the fender well it is a double plug. I pulled it out and there was a lot vacuum pressure on the line I plug it back into the relay assembly looking thing and have notice no difference. Was wondering if this was a cheap mod or somebody fooling a sensor? I read the DTCs still have P0470. Which I plan on cleaning it out when the time comes. Any ideas as to why so embody would do this and what does it do? It was plugged I to the red line. [/QUOTE]
