I am curious i have seen threads where people were talking about their car idling at low rpms after different mod installs? So now I am wondering what rpm should our cars be idling at?

Stock idle on my 1999 WS.6 was 800 RPM's when warm.

Up to 925 RPM's now.

thats good then......so cam will change your idle?
Mr. Luos

Yes.
Depends on the cam, the tune, the cubes, etc...


The cam itself won't change the idle, you have to have it changed.

oic you change it to meet your needs...or should i say your cars needs, you would change it to keep it from stumbling and what not correct?

~800 after the cam. It can go lower but it gets pretty rough that even I don't like it.

You're fine. Once warm there's 2 different idle speeds, one for Park/Neutral, and one for In Gear/foot on the brake for A4's. On a scanner stock mine was 645-676 P/N, 525-585 in gear. Tach was pretty close at idle.

Gear mines about 500... a little higher for park.. a4 here as well.. stock... but already have a shiftkit, 3600 stall, and DRs on the way... headers, cam, sfcs, stb, and true duals once I figure out what I want.. :D

850rpm. Cam doesn't change the idle, the tune changes the idle, allowing the cam to not stall the car out. With a mild cam the PCM will fix it on its own.
