Well I ended up replacing the coil pack!! Seemed be fixed for the last several days UNTIL TODAY I had left It idling yet again at the laundry came home turned off engine unloaded clothes, turned engine back over and it spit and sputtered misfiring!!! No codes are being thrown yet! The only other code that I remember from the first time was po0445 could this be the problem? I have an exhaust leak could it be the problem? I don't have the means right now to get to a mechanic or scanning tools! Should I change the o2 sensor next? Also I seem to have moisture or unburned fuel coming out of exhaust!! Should I replace the whole exhaust system including new cat converter?? Any information is greatly appreciated!!!!! Help help!!

445 is an evap code and will not effect your issue.
no, the exhaust leak will not cause this as well.
no, do not replace the O2 sensor. not until it is determined to be bad. I would start by cleaning the throttle body of all carbon deposits by the throttle plate.
