Thanks!!! Great information. I am going to change out the coils first and then keep the sensors in mind.
Yeah, the coils are suspect - and they have a history of slowly going bad. they seem like the weakest link of the whole motor.
But some of your descriptions of how the engine is behaving makes me think that a sensor or sensors may be bad - sending bad info to the computer - which then controls the fuel mixture improperly.
Oxygen sensor, temperature sensor, --- even a throttle position sensor could be bad.
More for you to think about.
