    I've had a couple batteries bite the dust before - never hurt my PCM or the tune...just bought new one and fired up the car. Idle will be grumpy for a few minutes until it relearns though.

    When one went bad it was so dead I couldn't even unlock my doors with the remote, and the rear hatch popped - weird. Where in MS are you? I was stationed at NAS Meridian when in the Navy, great tour - my son was born there - lots of good hunting and fishing too.

    Hey there, my hat is off to our armed forces, God Bless them and their families.
    I live near Grenada. I also hunt but never find time to fish. Thanks for the reply.
