At the time I had these readings I had a fault code showing misfire on 456.
Fuel Sys1: CL
Fuel Sys2: OL Fault
STFT B1 25%
LTFT B1 0%
STFT B2 0%
LTFT B2 0%
At other times I noticed that the STFT and LTFT for B1 and B2 mirrored each other so I suspect that the STFT B1 is probably indicating a fault.

You've a fuel system issue.
STFT = Short term Fuel Trim
LTFL = Long Term Fuel Trim
B1 = Bank 1
B2 = Bank 2
0% means that you fuel system is operating in open loop, which is to say that it is not adjusting mixture based on input from the 02 sensors.
Your car is running based on the factory preset fuel program. it is metering fuel based on throttle position for the most part with some input from the MAF and coolant temp.
Something is certainly arrive and I don't think it's the coil pack (at least not as far as the codes provided.
