My S will wiggle and will pull to the right when I change gears while accelerating more energetically. It will track strait otherwise. If I do not give her more gas at shifting, it is not noted. My tires are rather new, all are the same, I had an aligment last year. Car has 27k, never tracked or hit...What may be the problem? Thx.

 

Does it only do it on upshifts or downshifting (...decelerating too?)

 

Tire pressures? Our cars seem especially sensitive to it.

 

are you leaning on the steering wheel when you are shifting? Happens a lot

 

Hung up brake caliper... Does it pull when you brake?

 

Bingo... That was the culprit.Just by looking at the tire it did not look underinflated, but later in the day the pressure was low. Fixed the problem- it was a nail- and now she goes good. thx everybody
