I changed out all my sprk plugs and did the reset with the gap pedal. When I was digging aroud I noticed that one of the tube for the CCV has a tear in the elbow on the upper part of the tube. Will this cause the X5 to feel like there is a slight vibration during mild acceleration. When I put my foot into it it doesn't do it, it is only during mild acceration and only seems in the lower RPM range. Any help please.
