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

it would be important to note here that the gauge is reading -9.9, not -99, there is a decimal just like when you read boost (i assume you have yours set to read in PSI, like mine, jeff)

that wouldn't make much sense though....

-9.9 KPA is -2.9xx in/hg.
Which isn't even close to what an engine should read.
If you're only pulling that much vacuum, your engine wont' even be running most likely.
:shrug:
dunno, I don't have the gauge in front of me, nor am I a physics/math major.

-99 makes sense because vacuum gauges normally read down to 30 in/hg [negative].
If it is reading that, it just means the gauge is reading [incorrectly] to it's lowest reading.

thats because when you change the greddy to read in PSI, the - is no longer reading in KPA, im not sure what it reads in, ive been trying to find out through google but have had no such luck.

it somehow is reading in negative PSI, because -9.9 psi is -20.1589183 hg
