I just noticed that when I'm idling and press and release the brake my idle jumps up about 500 RPMs... it only happens when I release the brake though, not push it in....

normal? or no?

It happens to me as well, but it actually LOWERS like 100-200 RPM. This happened to me before when I had a bad brake booster, it got worse over time. It could be that, or one of the hoses going from that to the manifold could be bad or have a leak.
