It does matter and is the key to your concern. You have lost vacuum in the lines. The #1 vacuum leak on the o5 is on the rear of the intake. A small hose connects to the intake and has probably come off. If you don't know what you are feeling for, you probably will not get it on yourself. You may have to take it to the dealership to get it put back on. I say you have to feel it, because there is no way to see it without removing the upper intake. Either way, you will soon notice your engine not running correctly and then your check engine light will come on and produce lean codes. All of this is because of this one hose. If you have any further questions, feel free to ask.

Was this
