My 97 D-90 ECU has been creating a lot of problems and showing several pending codes. A local mechanic I take it to thinks the ECU is bad and I agree with him. Does anyone know where I can find a replacement or send mine out to be repaired? I have checked Ebay and only find D-1 ECU's for a Gems motor. My second question is will the D-1 Gems ECU work?
