Hi am06tz,
No problem, anybody can ask any questions and we at 2carpros will try to answer as best as we can.
Looks like the Service Check connector but for 97 models it should be OBD II equipped.
Some connectors are not used as they are for some other accessories which this vehicle is not equipped with.
If there is any misfiring, you would most likely feel some vibrations.
It is not easy to understand and advise on noise problems.
