Yeah, OBD2 is a different plug beginning in 1995 and is a completely different animal.... On the plus side OBD2 has a universally standardized plug and diagnostics platform. With an OBD2 cable and laptop software costing less than $80, you can plug in your laptop and look at all the controls while running the car. Re-flashing stuff is a little more involved and expensive.....
My default preference is carburetors and simple, self-contained distributors which steers me towards stuff that is now 30 years old!
I'm struggling to catch up with beginning of the modern era, which is now 17-30 years old. Troubleshooting this stuff is not much fun!
