Ok i was doing some cleaning.. i opened up the top off the air clearner and then lost the screw (my mistake).. then the bottom part of the pan that holds the air filter... is that supposed to come out without any screws? CUz i just jiggled mine and it came out exposing the tbi? Anyhow.. there were 2 hoses conecting to the air filter housing ... one was out to the left (facing the engine from the front, or passenger side) just behind the part of the pan that protrudes out and comes out to suck air... that was connected to the inside of the pan with a orange plastic thing made by fram it goes down and to the left some more where it conects to a thing with an indention on it right next to the oil dipstick.. what is that??...and what is the orange thing made by fram? i broke it i need to reaplce it lol. Second... what the hell is that tube there for? There was a second tube like thing conecting to the bottom part going stright down of the metal thing that protrudes from the pan this was not connected on by anyhting, what is that there for?.. im tryingf to desribe this the best i can i know it might sound kinda not clear. I see it all in the haynes manual but i cant find the names for these tubes.
