I took my car for a short half mile ride and came home and shut it off. It just didn't seem right when I took it for a ride. I don't know what didn't seem right , but the car doesn't feel like it was hitting on all 6 . I started it up again when I got home to take a closer look. there was some odd clapping, diesel sounding noise coming from the drivers side exhaust manifold, at least it seemed like it was coming from that. fluid levels were all normal. is this normal?
