So I figured out that by holding down some buttons when powering it up, my car's dash has some diagnostic modes. I have no clue what it's trying to tell me though. I'm wondering if it displays errors and engine problems.
Also, the set of gauges to the right (they display fuel mileage etc) didn't seem to have any mode like this that I could find.
Just went out to my 87 with 302 does the same thing

I need to check mine and see what's up. I have an 87' Tbird as well.
