Got my 04 s2k in April and noticed it pulls to the right when i accelerate to pass on the highway. Is this normal?If not any ideas whats wrong?

 

double-check the air pressure in your tires. Seriously. this it the typical cause for posts like yours

 

I would first check your tires. When I bought my 06 a few months ago, I noticed that mine would pull pretty hard when I hit the gas or let off suddenly while driving at a fair rate of speed. Turns out that the inside of my tires were worn badly. I replaced the tires and it doesn't wiggle at all now.
Here's for hoping it's as simple as that for you as well!

 

Might also want to get an alignment if the tires arent the problem. Ive noticed mines pulling right and had a mechanic check it. Told me it needed new tires and an alignment soon.
