Engine Performance problem
2002 Pontiac Firebird 6 cyl Two Wheel Drive Automatic

I have a 2002 firebird, it has always been a solid running car until recently. If i slowly accelerate the car will generally act normal, but if i try to get in it at all it starts sputtering and sounds horrible, oh it also seems to be burning much more gas than normal. I ran a diagnostic test on it and the codes were : misfire on cilinder 5, throttle body performance, and O2 sensor low voltage. I was wondering if someone could tell me the correct voltage that the wire running to the O2 sensor should have, or possibly why it says throttle body performance. I mean what could be wrong with the throttle body?

i am also having the same problem, code P0305, i changed wires, plugs and still missing, idles fine but when given throttle it starts missing and sputtering pretty bad
fuel filter is fine, fuel pressure is fine, no vacuum leaks at all anywhere, i checked the ohms of the coil and it was good as well, only thing i can think of that i have not checked is the ignition control module which the coil packs plugs into...
