P0420 is "catalyst system below efficiency". It means that the car thinks a catalytic converter is bad. It could be that the cat is failing, but it also may be that the secondary oxygen sensor (behind the cat, used as a comparator to determine the health of the cat) is failing.

The problem you describe is consistant with a tire problem. Could be as simple as rebalancing, however since it does not do it when you turn left, it makes this solution unlikely, but not out of the question.

When you turn left, your tire will tend to ride on the right edge, you loose the vibration, which would lead me to believe that your tire is "true" on the right side of the contact area.
