Hello and welcome to justanswer.com

 

When the restricted performance warning comes on the message center the ECM is in a default mode due to an electronic or mechanical problem and has stored a trouble code. It may be a problem with the electronic throttle, a vacuum leak or possibly an air flow meter. You will need to have the codes read with a compatible scan tool. I recommend that you go to your local parts store or autozone as they will usually scan for codes at no charge. Once you have the code numbers let me know what they are so I can assist you with the diagnosis and repair.
