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

have you checked the rubber hose right under the throttle body that goes to the idle valve?
you should also try disconnecting the harness plug that goes to that valve while the car is running, to see if your idle goes up. if it doesn't, then the valve or rubber hose going to it is the problem.

another thing to take a look at is your throttle position sensor. . if thats not plugged in or has been messed with, youll get high idle and that in turn will mess with your vac reading.

I dont know, I might have. I wish I had a JDM vac diagram so I can point out everything that I changed and things I capped off. I'm just not sure if I changed it with out looking at the engine. The engine is kinda far away right now.

I know I changed one fat hose under the TB that connects to the vac pipe. There is only three hoses on the bottom of the TB two for coolant and one for vac right ?

Isnt there a way to test it ? The TPS.
