So I have started to notice that while I'm idling my engine makes a click noise and revs to about 1000 rpms for about a second, then back down to like 900 or so. It does this only when I'm idling and every 10 seconds on the dot. I opened the hood to take a look and all I know is that it's a loud click and I heard a sucking noise when it revs up right after the click. Any ideas on what this is? Thanks
