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

when you did your boost leak test, how many psi of air were you able to fill it up to? did you spray everything down with soapy water and watch for bubbles?

there is a very strong chance that the leak is coming from the boost gauge. the nylon hose can crack during installation or your compression fittings might be leaking. another thing to check for is your intake piping, the idle hose that leads all the way to the throttle body, or your distributor oring. those can be tricky to find.

20 psi I sprayed everything with soapy water. After I was done I could only hear a very faint hiss from one of the valves on the throttle body. I can't remember the name of this valve at this time, my brain is not working today. I heard that was normal to have some air coming from there.

After I removed the Autometer with the nylon line, the vac was perfect. After a quick ride it fell a few numbers to like -95 -97. I should be at -99.
