That's exactly what I was going to say Joe, but let me add, just in case, about removing the vents as it can cause some severe trauma. Also, today, my whole car began shaking violently when it drives, idling is fine. It feels as if it's going across and endless road of speedbumps. Now, I know most people are going to say it's probalby flat spots in the tires, or possibly the belt separating, but I just wanted to get any other ideas before I went and yanked the tires off. So, any ideas? Thanks in advance Scott #16738
