Default Is this normal?

I just noticed my car acting a little funny. When I turn my steering wheel either direction the idle drops about 100-200RPM's. It does this while I'm driving and in neutral, I have a 6 speed. I never really looked at it before the cam so I dont' know if it did this previously or not. The cam is a cc503 installed in December, I had already had all the same bolt-ons before that. The sensors in the TB are both new too. Is this normal for you guys too?

the power steering pump is probably putting more load on the motor. the larger cam would make less power at idle so thats probably why you notice it more now.

Everything you guys said makes sense. I kinda thought that but I couldn't put it into words and wanted to make sure it was normal.

What about your idle going to where its set at? On a cold start the car takes forever to go down to the set 700rpm idle. When I start it in the morning to go to work it idles at 1200 and quickly goes down to 900-1000 and stays there for about 5 minutes. I even let it sit there after I start it while I buckle up and change CD's and everything, so it "warms up" for about 2 minutes. But even after that like I said it takes another 5 minutes of driving to go down to the 700rpm. Is that normal?

Your fine. The power steering is putting load on the engine and drops the rpms a little.

And your idle is fine too. The stock idle is like 500-600rpm, and is about 900 at cold start. So if your idle is set at 700, it should go to ~1200 and slowly decrease.
