Idle

At a complete stop (red light) I notice that the idle sputters slightly, almost to the point it is not noticed, but if you pay attention you can notice it. I can see the needle move slightly. I was wondering if this is normal?

Is the AC on?

There a normal "slight" dribble on the idle when the AC in on.

If not, your idle control valve might be bad. I had that problem and my car wa in the shop a couple of times to fix it (the dribble was bad). They first change the MAP sensor but that did not fix it. So they finally change the whole "e-gas" throttle body and that fixed the problem.

I know there is a thread on the Tech Forum on the Porsche Club of NA that discuss that problem. apparently the idle control valve get rusted and "stick". It sounds that you can just change that part.... but in my case the dealer change the whole thing.

P.S. this applies to e-gas, not sure for cable operated throttle body.

Thanks Frenchy! I basically notice it after being in traffic for about 45mins. I am not familiar w/e-gas? I will try and do a search.
