1986 GT Codes

OCode 63 is TPS voltage too low. You’ll want to check voltage at idle. Needs to be between 0.5-1.25v. To trigger the code means you are below 0.5v. This code can be an old stored cold, so you might want to delete codes, then rerun them after a few drive cycles

code 81 and 82 pertain to the solenoid for the air injection system. I assume those are deleted. You can ignore these without issue.

You’ll need a digital multimeter. Plenty of affordable ones on Amazon or Harbor frieght.

I would erase the codes and retest. Could be an old code
