I found an actual rat nest on top of my engine! When I removed it there seems to be parts/hose(s) missing. I can't find a goo pic of what is supposed to be there so I was hoping someone could fill me in. It's a '02 Ranger EDGE 3.0 Gas Automatic. I've attached photo of my engine. I'm pretty much illiterate when it comes to engine parts so I don't even know what the "circular sensor looking thing" is that looks like it's missing a hose. Does that just need a hose that goes to that red plastic "coupler deal"? Please help. THANKS!!!
