ive done numerous tune-ups and had my computer professionally reprogrammed and performance tuned. changed the spark plugs to the iridium ones and still cant figure out why i get a slight vibration while idoling can anyone relate to this problem or have an idea of what may cause such vibrations. i can feel it through the passenger seat and steering wheel. cadillac says it may be fouled up cadilidic converters but im not ready to spend the 2g's to find out that wasnt the problem any suggestion appreciated
