Few issues Options

[Defgeph]

From the begining of my swap I've had low vac issues. I replaced hoses tightened everything up capped off holes.

I eliminated my AC and power steering. I have the hose for the AC idle up capped. Would I be better off capping the two PS vac lines?(current setup) Or should I connect them to each other with a hose. I'm close to having full vac, but its still alittle off.

Second thing, when I slow down and put the car into neutral the RMP's dip way below normal idle. After running at like say 650-750 rpm for a few seconds, it raises back to 1000 where its been since the begining of this project. Sometimes the car stalls, I looking for some suggestions or ideas.

I've checked timing, its set at 10d's.


Thanks guys

jeff the 3rd hose under your TB is your idle control valve hose.
the other 2 are coolant lines, like you said.
guys say when you do the leak test to clamp off that hose.
your boost gauge is mechanical, right?
start the car up, and connect the gauge right in the bay, with a nice short hose and check the readings.

I'll also be trying that Saturday. I'm not happy with the little tiny nylon hose.

I think I'm going to re-replace that hose under the TB.
Can anyone tell me the size of the hose so I can preorder it and have the correct size ?
