High Idle
 

Hi, I bought an '85 RX7 a few months ago and I've been having high idle, anywhere from 1000-2000 rpm, it runs fine most of the time, but it has some issues starting sometimes. I believe it's a vacuum leak of some sort, but not positive. Also, my parking break light tends to come on from time to time, but shuts off after a bit. Any help would be much appreciated!
