We know there is a leak down further in the pipe (temp fixed it with aluminum sheets) but that would only affect the second o2 sens right?
Any exhaust leak from the exhaust manifold to the Converter inlet will upset the fuel mixture, That front pipe needs to be air tight with welds around the joints, Once its repaired or replaced pull the PCM B fuse in the Under hood Fuse Box for 30 Seconds then re-install the fuse and start the engine and see if it behaves differently. Also check the exhaust flange gasket where the pipe bolts to the exhaust manifold as that gasket fails often, Dont run the car with that leak anymore as the rich fuel mixture will burn up the converter.
