Check the circumference of ALL 4 tires closely, even 1/4" difference can cause that!

I did. They are all brand new. To add insult to injury, I even took the brand new michelins off my 400E and put them on it, same thing.

Not sure if this means anything, but when it was on the lift, I put it in drive, and the ASR immedietely kicked on and was braking the rear wheels (like it should be). My only concern was that I wasnt on the gas. Shouldnt ASR be inactive until the system recognizes the driver is on the gas. Could the sensor be bad on the gas pedal?

thanks!

Check the WSS ....specially as you are having ABS lamp as coming to a stop.

You can start with a DMM and spin the wheels..also ohm them for spec.
You can also pull them and see if they are full of crap and metal filings.

There is a good post about them from a few weeks ago..do a Search.

Found the post. Thanks! This car has been sitting for 3 years, so it very well could be a bad sensor due to rust. I will test them wed and report my findings....

If it has sat that long, I would pull the fronts and clean them, and also do the reluctors, specially the valleys..I am sure they will be full of crap too. Then spray some brake cleamer in the sensor hole as you spin the wheel..that should clear them up...
