Ive recently replaced my battery in my 03 Mustang GT. Every since replacing the battery, it doesn't seem to run like it use to prior to replacement.


Should I get it re-tuned or is it just me ??

Please I need Information

I'm thinking it's you. Have you had your car tuned by a handheld tuner or a custom chip?

i think its just you being paranoid...we all do it!

can you be more specific about how it runs?
