When I am driving and I put the car in neutral and coast and the speed goes down... I notice that the RPMs go up and down once it reaches a certain point.
It does NOT do this when the car is stopped and not moving and is in idle though.

Is this normal and is because of the cams or is it something that is not normal?
Thanks

I have a buddy with the Hot Rod cams and his does a similar thing at the lower RPM's. I can't remember if this is exactly as he described but it sounds similar. I know I didn't really answer anything, but at least you know you're not the only one :-)
