98 OBW chugging/sputtering

If I were you, I would check: (1) your spark plug wires for signs of wear; (2) terminals on the coil pack for corrosion; (3) air filter to see if it's dirty (even a little); and (4) replace the fuel filter if it hasn't been replaced w/i about 15,000 mi.
Those are the cheap and easy things to start with and to rule out.

I have a 97 OB. I've suffered this issue a couple of times. The problem... carbon. These things run rich. It took a MotorVac treatment to cure mine. Since then, an occasional tank of premium or some good gas cleaner seems to keep it in check.
Recently, it came back and I couldn't 'cure' it. I had the O2 sensor changed. It took a while, but the car is back to it's non-sputtering (hesitating) self.
All the things Chip mention could also be the problem. But I thought I'd share the one that most people don't think of (and should NOT expect) in this day of fuel injection and computer controlled engines.
