My son had an engine replaced in a '01 LS. Now the car wont pass emissions. on 2001 Lincoln LS

Engine came from a Jaguar(that's all we know) and it is giving random codes like different cylinder misfires and bad oxygen sensors although they were all replaced. Mechanic said there was a problem with the harness. Any of this makes any sense to anyone out there?
