Oldsmobile. There's a group, but it's not too active. The same engine,
a "Y" code 307 V8, was used in some Cadillacs too.

If your car is 1994 or later,the electronics stores codes relating to your
engine problems,Autozone will read the codes for you at no charge,I've
heard.

There's an Autozone near me. I have seen them go out to the parking lot
to do just that for a customer. My car, an '89, has the CCC system, not
OBD II.

Thanks.
