What is this [Tube]

Off a 1987 Coupe

It was in my box-o-spare-parts, its part of the emissions, but thats where my knowledge ends.

Thanks.

It looks like the one that runs down towards cylinder #2 where the tube for the cat connects to.

Looks like a vaccum/EGR tube or something.

I like the EGR idea... or perhaps part of the air pump system...

It positively is the tube that runs through the A/C mounting bracket (with the fuel lines) from the AIR switching valve to the AIR line which goes to the middle of the CAT. I recognize it because it gave me fits trying to get it back into position after my engine removal and re-installation.

Right on. I had the same problem on my '86. It came out relatively easy, going back in was a real PITA!

AIR pipe that goes from the switch to the converter. Had it apart today and re-did hoses and clamps.
