996 idle off gas pedal issues
Hi Folks,
I,m new to the 996 world and having taken the plunge on getting one. I'm having an issue with my idle which I think is pointing towards an over vacuum situation.
Having done some extensive rebuild work (engine out), I have replaced the AOS as I was advised it was good practice with engine out so as its new I don't think that's the issue (even though it can't be completely ruled out).
Whats happening is that on start up I need to give it a little gas to maintain idle. Once its warmed a little it appears to idle fine, however if I give it sone rev,s and take the foot off, it drops just below idle and usually cuts out. If I take my foot off very gently, idle is maintained.
I,m think towards a very slight over vacuum as I would say it idles slighty better (when warm) with the oil cap off.
It will sit at idle fine if left alone once warmed a bit.
I did also notice that the intake flap sits practically closed at idle and wondered if that's natural.
Any pointers woukd be appreciated.
Thanks
Simon

May u should give us some basic details about your car like maybe...... whst year it is? Yes it matters.
most likely u need to smoke test the intake and find your leak. Also there is a icv, idle control valve, that may need to be cleaned or replaced.

What? What? Are you an alien or do you live on another planet? Do the normal laws of physics not exist where you are? What you are saying makes no sense. Pull your throttle body, remove the ICV, clean it, cycle it with a 9V battery. It should be shiny and clean on the inside.
