what is this? i have looked all through my "haynes" manual and can't figure out what its for?



Talking about the small valve with copper vacuum inlets?attached to LIM, between the secondary injectors.Thanks



*edit* oh....in case any one was wondering- The items used to replace the fpd are from my honda

 

Sub zero assist valve - throw that thing away and block it off with a plate.

Mazda even recommends this.

yeah, the brass piece is broken on mine, i really need to block that thing up.
