Thank you all...

My 350z not starting did turned out to be a battery issue. I jumped my nissan and it started right up... You where all correct on the battery issue!!!!

Second issue (rough idle) feels like the car was running on 5 cylinders... Found out I was running on 5 cyclinders. Tuns out when I replaced my spark plugs I did not properly snap the connection to the coil. My friend found this issue.. A second pair of eyes always helps!!!

Thank you all again..

Car runs great!!!! Tine for the next Mod!
