My old 95 Turbo Talon had obd2.
Some cars had it and some didn't. Hence the 'ish.

Re: OBD 1or2??

The cars that this forum is devoted EXCLUSIVELY to - 82-92 Camaro/Firebird - were ALL OBD1 if they were even OBD at all. Some (notably export ones) were not. On this forum, no other vehicles or motors matter.

For a 95 motor in a S truck, I suggest you visit forums dealing with 95 motors and others dealing with S trucks. Neither of those things is pertinent to 82-92 Camaro/Firebird, no matter how much you may have come to admire or respect the level of technical knowledge some of our members here may have.
