Over the last day or so I've had a couple problems with idle speed. When I start my jeep, it starts with no issues, but then idles very low...say like 200 rpm, whereas it is typically up around say 600-700 or so. Basically, its borderline stalling (it does stall every now and then, but not consistently).
When it first happened, I thought that it might be a vacuum leak. Thing is, it doesn't happen every time, and I can't reproduce it if I try...it seems completely random. Sometimes its fine. It runs perfectly when not at idle, and when I have the idle issue if I blip the RPMs up a few times it then goes away.
