I recently bought a 07 TL-S with a 6 Speed. When driving the car seems to go straight, although the steering wheel is a little offset to the left in order to be able to straight. When I step on the gas, at pretty much any gear, even on 6th while doing 70mph the car pulls to the right.. The steering wheel doesn't turn it just drifts to the side it seems and I have to correct it then once I let go of the gas it snaps back into lane. It gets annoying cause when I accelerate I have to compensate with steering and then when I let go of the gas I have to steer again to get back to driving straight.. so it looks like I'm driving drunk or something. Its got brand new 18inch tires (car came with A-Spec rims) so I dont think its the tires causing it. The breaks are brand new as well, car's got 50k on it. Any ideas on what could be causing this?

 

Alignment for sure and possibly broken compliance bushings. There's a good chance something is loose too.

This is how my car behaved right before the lower control arm bolt fell out so you may want to get it looked at quickly. Mine would actually turn left hard when braking and pull hard to the right when accelerating and my problem was on the passenger side.

 

I didnt read the rest. this tells me you need an alignment.
