what did you do with all the oses and stuff that go to it?

[sippin.fnordies]

i removed all of it... rougher idle when cold, but as soon as it warms up I have no issues.

just make sure you block off/re-route any unused vacuum lines etc.

I just installed a catch can so I have a more functional PVC system instead of the filter venting to air (after 4 mos or so the filter was dripping oil and not really ideal) Ill try to get pictures of my engine bay with that in soon too.

okay cool. and what about the little sensor on the back fire wall?

I eliminated them altogether

But then, none of my vacuum system is stock.

The sensor with the two hoses going into (or three for AC-cars) just below the vin plate on the firewall?

That is a solenoid valve that's supposed to bump up the idle - one (and only one in non-ac cars) opens when idle is below 850rpm I believe. The other opens when the AC is on.

Little effect if removed - plug the lines that would go into it or rer-route them if you need them for something

okay thanks. i will get to ripping stuff out this weekend.

I removed all that stuff a long time ago including the valves mounted to the firewall. To combat the rough idle when cold I hooked up a mk2 isv and haven't had any problems. I think I routed the evap hose (the one that goes back to the tank) to the throttle body... Don't quote me on that though, its been a while since I did it.
