I'll bet you a cookie one of your O2 sensors is actually the problem- ie: fuel trim is off because the ECU isn't reading air/fuel mixture properly .

Ok, but how do i find out if that is indeed the case??? And would this explain my misfires? And how would this only affect one bank of injectors......and which bank is Bank one?

Adam Is there anyway you can get the Front O2 sensor voltage? also the correction rate could help. ( the dealer can get this just tell tehm that you need the freeze frame data)

Not sure if the dealer will charge you or not. Depends on your relationship with them. Maybe you can offer a ride when its done. The correction rate is how much the ecm has to correct the A/F ratio. It should not be higher than 25%

Takes about five minutes to get the info. They probably can even tell you if the sensor is fried or not.
