Was taking out the battery today and saw a flat gray tube coming up the firewall so I tugged slightly on it to see what it was attached to and it broke off where it was attached to a very small light green tube. It goes toward the passenger side strut tower connects to a thin black tube that circles back around along the firewall and connect to a sensor on the TB. This sensor has 2 other vacuum lines coming off of it. Not sure what sensor that is? I think the thin green plastic tube behind the engine might go down to the transmission? I didnt go under the car to see. I will find some different vacuum tubing to fit (hopefully) and reattach as the current gray vacuum tubing is flat and doesnt seem to actually allow any flow of air. Just curious as to what this is for.
