confused about vacuum line

[ja23merz]

on the back of the intake manifold, there's two places where vacuum lines are supposed to go. i checked the diagram, and the top port has a cap, but the bottom port says it goes to a solenoid(for AT only). i have a MT, so what am i supposed to put there?

Just cap it. The nipple is for the Auto rear transmission mount.

[cp[mike]]

it varied due to differences in the cars, be it MT or AT, if it had cruise control or not, etcetera.

usually the lower nipple on the back leads to the black control box for the secondary intake runners on the F22A6 manifold.

if it ends up you dont have anything to use it for, just cap it.

[demortey@mac.co]

just block it off with another cap or modified piece of hose or something. that's for the adjustable tranny mount that's supposed to help with the 'honda shudder' when you're sitting at a light with an auto.

[ja23merz]

hmmm, alright thnx for the tips guys.

uh.. since we're here, I have a f22a6, /w auto, and it shudders alittle when idling @ a light, is there something I can clean or adjust to fix, Ive got near 200k on the clock and runs very well.

maybe your rear engine mount is done for...

Not to thread jack but does anyone have that same Diagram for an H22A

[angus67]

thanks ghost, will it be obvious? or do I like shake it or something?

probably it. pretty common problem with the auto trans mount.

I had to replace my rear mount because of that same issue, and no it wasn't obvious. I basically just took it on faith that that was the issue. But if you think about it, it is a good idea anyway, that mount is at best a 15 year old mount with 200k miles on it, there's a good chance that is the problem though.
