vacuum problems.

[the pony boy]

well after installing my hci last year the car never ran rite.it was faster but didnt idle good and ran ruff.after studying vacuum routing i figured thats were my problem is.as of now i am feeding the egr and fpr from the lines that come from the pass. side strut tower. but im not giving it any vacuum from the manifold.im using 2 ports from there and blocking the other 2.my fuel pressure doesnt change(electric auto meter)either im assuming cause its not getting any vac.now if i feed the fpr vac. from the manifold and feed the evr so it can work the egr should i be ok?also does it matter which port i use to feed the evr?i aslo have no smog.ive searched a ton and have learned alot(i think) and im just trying to see if im on the rite track. thanks alot phil

Vacuum line connections:
One large vacuum line from the upper front goes to the carbon canister

One large vacuum line from the rear goes to the vacuum tree.

One small line in the front feeds the Smog pump solenoid control valves on the rear of the passenger side wheel well..

One small line in the rear goes to the fuel pressure regulator.

One small line in the rear goes to the EGR suction regulator.

One large line in the rear goes to the PVC valve.

thanksjrichker.i dont have smog so i dont need that.what i come to find out is that i was never feeding the EGR suction regulator (evr).i was running 2 lines from the coupling on the pass side strut tower to the fpr and egr.so neither one was getting vacuum.im going to play with it now and see what happens. thanks phil
