Hello. My name is ***** ***** I am happy to assist you today. Give me just a moment to review your post, and I'll be right back with the help you need.

The problem you are describing is likely caused by an engine misfire and that would also cause the restrictive performance message to appear. In order to determine what is failing the first thing your going to need to do is to have the computer system scanned to see what the fault code and or codes are that should be setting. Most auto parts stores such as Auto Zone will run a scan for you at no charge. If you can get this done and post back with the results I will help you get this figured out and resolved.
