I found the problem.....the dealer did not do what they said they would do.....I asked them to check the air pressure in the tires last saturday when they did the oil change....they stated a few hours ago, that, the pressures were set @ 32 psi......they were partially correct.....3 of the tires were at 32.....one of them, the left rear, was @ 12...yes, 12.....had a tiny nail in it and was just barely leaking and over time it had leaked down to 12 psi and the dealer didn't bother to check all of them.....if he had properly checked them before the alignment was checked, as your supposed to do, then he would have found the low tire....I hate dealers sometimes....

He drove it all the way down there like that from Cleveland! 
Tires and wheels were installed by "professionals". Just remember, just because the job was done by professionals does not mean that it was professionally done.

That guy isn't driving anywhere for awhile though.

I understand that a low tire will cause pulling in the direction of the low tire....what that doesn't explain is the car pulls the opposite direction under acceleration....I'm thinking it's a differential, halfshaft or rear suspension mounting issue....
The low-pressure tire has a smaller radius than the properly inflated tire. When at a steady speed, the S2000's limited slip diff acts like a regular open differential so the fact that the low-pressure tire is rotating faster doesn't matter.
As soon as you apply power, however, the LSD does its thing and limits slip... So the tires are rotating at the same speed, but one of them is smaller than the other - in essence you're driving on an ice cream cone. The car pulls to the side that has the low pressure tire. Counter-steering will correct this, allowing the car to track straight under acceleration.
Then as soon as you let off the gas, the car will just go straight on its own, however the wheel is turned to the side some and the car ends up pulling in the oppostire direction until you correct everything.
