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

Update:

I checked the boost gauge as suggested by Manny. It turns out the nylon line connected the the boost gauge was leaking. I always hated this nylon line.

So I replaced it with a rubber hose. The vac reading is now normal on the Autometer. The Greddy on the other hand is still fluctuating. Funny huh?

I did a spark plug change, Still ran alittle rough at times(idle after boosting) but doesnt stall anymore. So I think after a regap of the plugs I should be all set.

I just dont get way the Greddy's vac readings are all over the place.

But thanks for the help guys, it's running alittle better now.
