Only had my 03 Z for about a week and not sure if this is normal but there is a very slight intermittent idle rock, nothing like a constant misfire. Are these things supposed to idle like a sewing machine or is this intermittent idle rock normal, no codes and it runs great.

It's normal. Our Z06's come with a more aggressive cam than the LS1 counterparts.

You'll come to enjoy it, if you don't already.

Both of the LSx cars I have owned did this. It is just part of having a large engine and good motormounts...

Thanks guys. Glad to hear it's normal.
