I've noticed that my steering wheel shakes when I begin to accelerate. As I increase acceleration the shaking lessens, but this just started? Any ideas why?
Also, on occassion, usually when driving for over an hour or carrying a heavy load in the trunk, acceleration can get sluggish- non responsive..it inches up very slowly...hovering in the 35-40 mph and then kicks in to higher speed. Why does that happen. I get especially nervous on the highway. This only happens after a stop (say at a toll booth or a light) and trying to regain speed. (but not always) but frequent enough for me to notice.
