want to remove the acv will it cause problems?
well ive decided to remove the acv to see if maybe it will fix my boost issue.It seems that everytime I remove the acv and put it back on the car runs well for a short period of time and then runs like crap again.
Is the acv essential to passing emissions? im still trying to figure out what exactly the air control valve does and how its linked to the egr and air pump setup.
Would I be able to run a downpipe and highflow cat without the airpump and still pass the sniffer test? just a few things im worried about right now.
Ive looked over the vacuum diagram and from the looks of it In order to remove the acv I will need to eliminate the relief 1 solenoid valve and the switching solenoid valve and the vacuum lines associated with each.
I was thinking of removing the egr as well but im unsure if there will be any negative effect by doing this as well.
Just need a little advice on this.Thanx

You will not pass emissions without ACV and airpump.
EGR and ACV do not interact with eachother.
The ACV directs air from the airpump to exhaust ports and main cat when needed for emissions purposes.
You can remove the EGR with no ill-effects, provided that it is not an electrical EGR.

thanx jonski for the help.So even if I kept the airpump it does me no good since the acv is the part that distributes the air that the air pump sucks up correct?

do I need resistors for the acv wire plugs ? theres 4 of them I believe.If so what kind do I need and where can I get them? the same question goes for the egr solenoid harness plug the switching solenoid wire plug and the relief 1 solenoid plug wire.Thank you.

The only resistor I used was for my AWS. For the solenoids on the rack, I just placed them back on the plugs with no vacuum tubes connected to them, but this left a mess. Next time I'm in the engine bay I'm going to replace them with resistors.
For resistors, use something between 330 and 360 Ohms.
Half-Watt or greater.
Preferably flameproof, but not really important.
