Honestly its not a bad idea to change the fuel filter if you never had just as a course of good maintenance.

It is possible to check fuel pressure and see if the fuel system is the problem.

Any check engine light codes?

For my 97 it was always the plugs, coil packs or wires. There is almost no limit to the possibilities though.

So I guess, any codes?

No codes and I dont know how you would go about checking fuel pressure

You gotta buy one of those kits. I'd tell the counter fellow you own an Oldsmobile in the event GM cars call for this size or that size adapter.. MAYBE the parts store will rent one out?

It could be a lot if things including the fuel filter. Plugs, wires, coils, fuel pump, vacuum leak, etc.
