just started happening. not sure what it could be.
any ideas.

i think alignment, but its wierd that its different when on and off the gas...

 

Check your tire pressures.
On all four tires.
When cold.
9 out of 10 one of them is low.

Let us know what you find.

 

Either this(rear tires),or your alingment is off.

 

My first thought! Usually if it pulls one way during acceleration and it pulls another way during deceleration, a tire is low on pressure.
