Has anyone else ever experienced a rough acceleration noise from their lsj? While I'm driving, if I begin to accelerate, I hear a harsh ticking sort of noise. While cruising, the noise isn't there, because I'm keeping the rpm at a certain point. Also, when I'm standing still and just revving, there's no ticking or harshness, only a sweet supercharger whine thanks to the airbox mod. Could it have something to do with my serpentine belt considering it needs to be changed? There's no exhaust leak from what the muffler place told me.
