Hey guys. New Gen1 owner here. I have a nagging issue. I get a Bank 2 Sensor 1 error. I changed the o2 sensor/heater, cleared the code and I was good. However, the code comes back any time I put it under load like towing my boat. If I clear the code and don't tow it doesn't come back. I had read that it may be a manifold crack on the passenger side. Thoughts?
