  1. Okay I'm getting trouble codes of 26, 51, and 62 51 is the PROM code
    Anyone know where they stuck the ECM on that car so I can see if it's
    loose or should I just flat out replace the PROM. Any advice would be

  2. I've found typically ECMs are located behind the passenger's footwell
    kickpanel, however that may be driver's side in your case. At least thats
    where two of the three EFI cars I've got serious with have had the ECM

    Fieros hide them behind the centre console... hehe! And Honda like putting
    them under the seats!
