RE: 96 deville

Bank 1 odd numbered cylinders. Bank 2 even numbered ones. Bank 1 Sensor 1 is on rear exhaust manifold. Bank 2 sensor 1 is on front exhaust manifold. Bank 1 or 2 Sensor 2 is after cat.conv., or on effected side if there are 2 cat.s Bank 1 can vary depending on engine layout, but it will follow the #1 cylinder.
