I would definitely look at the fuel system first. There is one little part that seems to be overlooked alot, and that is the fuel pressure regulator. If it's fine and your pressure is good, check the injectors for pulsing.

The one part I might add to the equation is the opti harness. But at 235K, I really wouldn't call getting a new coil, icm, harness, and cap and rotor neccessarily "throwing parts" at the car. These are considered maintanence items, and it's probably time.

I've been there. It's your optispark. I'd bet on it. Sorry, it's not what any of us want to here.

Yup. May as well change it and get it over with. Not too hard to do, IMO.
