Engine torque can twist the frame when you attempt to accelerate rapidly. A loose or broken motor mount can make the effect even worse, to the point that it effects your steering. Get it checked out.
Low air in a tire, weak brake, bend steering, could be several things. Start with the tires, as that is the easiest, & swap the two front tires.
It still could be the alignment or it just gives more power to one side.
I just noticed this the past couple of days. I know its not the alignment because if i have my foot off the gas, i drive straight as an arrow and even when i am pressing the gas, but not gunning it, it goes straight. I only notice it when i hit the gas off stop signs and lights, or when i have to get on the gas to pass someone. I was thinking maybe a bad caliper causing a brake to drag, but then it should still pull all the time. Any ideas on what it could be?
