After changing the battery on my 2006 Ford Mustang gt with 5 speed manual transmission it idles very rough and sometimes dies during driving or idles so low the power steering is not fully functional resulting in excessive steering effort. The car ran fine until the battery was replaced. I followed the relearn procedure in the owners manual but it did not help.
