The blue disk on the the front whel well (under the hood) is, I believe, a component of the vacuum system that assists in the shift timing of the tranny. Does this item take its readings, at least in some degree, from the same line that runs from the intake manifold to the ALDA?
Does there exist on this palnet a schematic of the vacuum systems for these cars? Haynes is ridiculously deficcient on this.
Thanks.
