PCM/ECU replacement
 

Looking for some help...My daughter's 2010 9-3 has misfire codes for each cylinder and we are being told the PCM is probably the cause. Can anyone tell me if mailing in the PCM/ECU to be cloned is a good idea or recommend a better option? We live in South Dakota and I can find anyone in the area to program a new PCM/ECU. Thanks in advance!
