Flatline1980

Today i jumped in the car took her for a spin to Mom and Dad's and she ran like a friggin top.. Tonite i had jumped in to make a run and she wouldn't do crap.. Earlier today, i hooked up my sct3 to adjust the tire/rev and now i get codes P0607 & P2107.. I changed the battery a couple months ago.. What research i'v got to do tonite (before i go to bed, what luck), my 07 ain't the only one thats done this after a battery change.. P0607 seems to be an Alt.. Would this happen to also be whats throwing the P2107?? Any other suggestions will be welcomed.. Thanks folks in advanced.. I get to go to bed with this on my mind.. uuggh.. worst luck ever..
