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.

good ol autometer strikes again.haha.

you have to remember that the greddy is probably reading a lot more detail then the auto meter. my blitz reads .65-.70kpa depending on time of day, weather, if i have my headlights on , idle speed, etc... when you convert that over to vac, its really somewhere around 19-20vac difference.

i hope you dont mean that you want to regap the plugs after you just put them in? the ground strap could break off if you regap after they have been used already.

what rpm is your idle at now?
