Hi everyone:

I have a 2006 X Type over the weekend the battery went dead. I checked the voltage output using the onboard diagnostic center. The voltage varied between 14.2 and 13.0. I changed the battery this morning with an after market one. Everything worked great but after about 100 miles I noticed a miss on low end and at idle. Check engine light came on and I pulled the codes P2A01,P2A04,P0101,PO300, along with a misfire on 1,3,4,5 and 6 Any ideas and could the battery cause any of this. Any help would be great

Thanks Scott

P0101 is voltage related, but that's as much as I know so hopefully the list will help someone else figure them out for you
