Injector valve 1 low voltage c20xe

:shakehead Please help me! my astra 1993 Gsi 16v (c20xe) has failed co emmisions in MOT (too high readings that get higher as it revs up). a fault code has come up and I used the "paper clip" method and read code 81 which means "injector valve 1 low voltage" Shall I replace the fuel injectors or what? How can I solve the problem?
