Try ohm testing your injectors, a failing injector will act just like that. Post up the results of the test.

symptoms of the opti that i know of are ignition cutout which can be at any rpm but most notable under load at low rpm in high gear if it's a manual or at high rpm wide open.
And also the car won't start especially when it rains or after it rains and is damp.
if you have these symptoms, or if you know the opti has never been touched then you most likely need to service it.
there's an optispark writeup on the web I remember reading where you don't have to replace the entire thing for big bucks, I think you can clean it.

also, car jumps fro under 1000 to over 1000 constantly while idling, and gauges start to act like the car is dying...
