    Absolutely there is a way to access the codes. But you need a diagnostic tool to help you with that. With the tool, a technician can determine what codes you have, and then pursue a diagnosis.

    I suspect you probably have misfire codes from cylinders that may have coil issues. Also, the 3.9L V8 engine in your Thunderbird is prone to having the valve cover gaskets leak around the ignition coil holes. The oil getting on your coil boots can cause them to degrade and cause a misfire.

    Just a random thought - I cannot say for sure without testing what the issue you are having may be.
