I'm trying to find a vacuum diagram (image or illustration) for the vehicle listed above, the vacuum lines were disconnected. I attempted to put them in their appropriate locations but failed. I ended up getting a sucking whistling noise and having brake vacuum booster operation issues. Any help would be greatly appreciated!

Hi,

I attached the vacuum schematic for the evaporative emission system (pics 1 and 2).

Pic 3 shows the vacuum supply to the vacuum brake booster.

Can you tell approximately where the noise is coming from? Also, let me know what is happening with the brake booster.

Take care,

Joe
