Fuel started making a noise..circuit

Customer Question

Had fuel injectors replaced and the mechanic put the wrong one in and car started making a noise. Put right one in and noise is still there. Mechanic said that a circuit may be bad, is there a way this can be fixed? Q45 1994

If the mechanic used an injector that has a lower resistance than required, there is a good chance that he burned out one of the injector drivers in the computer. the only way to fix this is by replacing the computer or having the computer re-built to repair the injector driver.

Will another computer work out of the same year and do it need to be programmed?
Expert:  Alex Armfield replied 7 years ago.
it should be plug and play as long as the part number on the computer is the same. you shouldn't have to program it.
