Vacuum question/ problem

1089 Views 12 Replies 9 Participants Last post by  EastTennBimmin
ok so i have a little problem i have a place on the back of my intake manifold where there should be a vacuum line so i caped it and after i did it made the car start idling low and almost dying out so i took the cap of and it started idling like it has been again at around 800-1000rpms very confused as to why it would idle down with it on but be fine with it off.

The only repercussion with it off it whistles when i get around 5000rpms, but i did drive it a little with the vacuum cap on and it seamed a lot fast with it on but won't idle not sure why and advise would be helpful. :thumbup:

also this is on a honda civic with a b16b with stock civic type-r intake manifold.

also here is a pic of the vacuum port it is on the back left off the intake manifold near the brake reservoir.

Put the cap back on it, reset the ECU, adjust throttle according to Chiltons / Haynes
There is a Chiltons / Haynes books for C.T.R's....?;)
No way!!!
