|Think of what happens when you turn left. What happens to the car? It dips a little to the left and the right side rises a little. Just the opposite when you turn right.
I'm with Dan on the cause. Fuel related. Time to check the floats and level of both cards. Could be one of the floats has a hole causing a difference in the height because of the added weight. The floats are out of adjustment causing an issue when you turn left.
