Hey everyone. I just bought a 2009 wrangler X 3.8 v6. 45k miles. Runs like a dream, and I love it. When it warms up I'm hearing what sounds like almost an electronic blip or chirp (not quite like a loose belt) under the hood that happens intermittently when idling, and speeds up with more throttle. It doesn't sound like a ticking or anything serious, but it is annoying. Any ideas as to what it could be?
