Can you advice the proper OBD1 code reader scanner for above vehicle?

Hello,

For your Acura you can use a Car quest 30435, OBD I dedicated scanner. This will only scan OBD I vehicles from Acura, Honda, Nissan and Toyota.

Another good option is to use an Innova 3120, this will do OBD I as well as OBD II. This has a much larger coverage.

Please let me know if you have any questions.
Thank you.
