Is this a defouler? Intake manifold vacuum line

[Bhudzallmighty]

I removed both by o2 sensors for my lx450. The picture below is the rear o2 sensor. Is that a defouler? Voltage for both my sensors are 0.05-0.13.

The second image is the intake manifold vacuum. For what I understood, that vacuum line is sealed off in supercharged 1fzfe? That will not cause a vacuum leak?

Thanks

That does appear to be a anti fouler. Do you mean OHMS not voltage? Per the FSM the O2 sensors should measure between 5-6 ohms of resistance.

As far as the vacuum port I can not answer that question. If there are no loose vacuum lines around I would cap it off and see if that makes a change to the way the engine runs.

Second picture looks possibly like coolant line. The other end is below the throttle body and connects to the head. Bet it's capped.

Scratch that. Now that I ponder I think coolant is on the TB itself.

Dunno but why does your Audi have rubber bands for tires?

Looks like a toy/power wheel

That port is capped off on our ‘93 as well as ‘97, each with S/C.
