not 100% what i should be pulling at vacuum at idle on my car, but im seeing about 10 on my gauge and idle is very low/choppy. i "think" it used to be close to 20, but since i added the 1" spacer between the manifolds, my vaccum/idle seems to be all off. i treid changing the TPS and cleaning the IAC so far also.
on the Vacuum tree, i see that one of the lines/caps has fell off or is missing. what goes to the "B/R" spot on the tree. i have:
-BB runs to the brake booster and is connected
-S/C is capped, should i run my boost gauge to S/c possibly?
-A/C run accross the firewall to what looks like another vacuum tree
-B/R was missing, but i capped it and didnt seem to make much of a difference
-and S runs to my upper intake manifold.
Also, i have a mystery Vaccum line that streatches the firewall also. dont know where it goes, but it looks like the origin is the fenderwell behind the passenger shock tower? its hard black plastic and what looks to be a "bigger" vacuum line. i "dont think" it was hooked up before, but i could be wrong
