There you go then, until the O2 sensor fully warms up the engine will run open loop, if the O2 sensor is faulty which the code says it is it may then provide duff fueling data when it begins to operate after 5 -10 mins.

Buy a reputable O2 sensor like NGK or Denso and replace it.

Yes it's the 02 sensor. The cars even trying to tell you this with the fault code. It's goosed needs changing.

Your car is shuddering because the 02 sensor regulates the air/fuel ratio into the engine. Now if the 02 sensor is broke, it can't adjust air fuel ratio correctly so your car will judder it's either getting not enough fuel or too much or not enough air or too much.
