That is not a common problem on that car. I would take it to an experienced repair shop and have it properly diagnosed. Autozone only "reads" the codes. The problem still needs to be diagnosed.

By coincidence they sell parts to , right? Take both of the other suggestions and get it diagnosed FIRST , before guessing on parts.
