Vacuum issues :( steering related? :S

[slystiguy]

EDIT* I have changed topic to update with a slight issue i'm having. Anyways here we go

So replaced vacuum lines (see below) and car boosts great now runs all the way to about 17psi and comes on alot harder. How ever I have a very minor niggle that is kinda bothering me. When cold and only when cold it seems to have a drop in vacuum? e.g its idling nicely then you go and move the steering wheel and the revs drop an the idle sorta splutters abit. When the car is hot it does not have this problem and every other aspect of the car is working as it was apart from the cold idle. The only thing changed was the vacuum lines. I went from the stock lines to a 4mm silicone hose with cable ties on every join. I did not keep the factory adapters on could this be the issue? (the adapters that go from 4mm to I think 6/8mm).

I will also note the car seems to idle about 250revs lower than it did before when hot

Any help would be much appreciated

So when I was taking off my old lines today to fix a leak I noticed some pipes start at 4mm hosing an go to a larger size via a lil plastic adapter. I've removed this completely and just gone straight 4mm silicone hose. Will I get any problems doing this?

Note: I know about the restrictor pill so no worries there

I too wondered this while doing something similar recently, although I kept the status quo to be on the safe side

bump still wondering if this is going to have an effect on car. Might get some bigger hosing and put back on just to be safe

did you damage the power steering torque sensor thingee (technical term) on the P/S pump? the wire fell off mine without much effort.

Its there so when you turn the steering wheel it bumps up the idle a little to stop it spluttering and trying to stall.

Hmmmmm I didn't think I touched much but I guess anything is possible... Will have a good look at it
