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

A boost leak won't affect idle quality at all.
A vacuum leak will however.

Jeff, if you join those 2 hoses you will raise your idle.
One gets air from before the TB [intake hose] while the other runs off the intake manifold.
Basically you will be creating a second ISC valve, but with no valve.

For both of you, how does the needle in the gauge look?
Is it steady at low pressure or does it jump around some?

If it's steady it's more of a general problem, such as a weak coil, or vacuum leak. Or a worn out engine.
If it's jumping around it's more likely to be from 1 cylinder, such as a bad plug, worn ring, or bad seal on a valve.
