I took my air filter out. On top of the air filter cover is a soft big black rubber hose that goes to the valve cover. There is a very thin brownish pasta colored hard plastic hose/pipe that splits off from the big black soft rubber hose. Just by touching the thin plastic pasta colored hose/pipe it snapped in my hand. What the heck is this thin hard plastic hose/pipe and what do I do now? LOL Where did it go to? Please help me. I'm trying to fix my car not make more problems.
