This annoying "chirp"
I've had my mustang for a little over a year and I love it. It took me a while to get use to a V6 vs. V8, but this car has proven itself. I went ahead and added a few things to it and I'm fixing it up little by little. I just put a Bassani XHaust on it last Saturday. But there is this annoying "chirp" coming from somewhere under the hood when it's idling. I don't think it's hurting the car but it annoys the hell out of me. It was doing this way before the exhaust and before I put my CAI or tune on. Does anybody have any ideas?
