Why are all the lights on the dash coming on while I am driving? on 2006 Chrysler 300

I had the EGR and Knoc Senor replaced but while driving all the dash lights will come on and flash repeatedly.The check engine light is on and no one in the area can detect the problem.

I am sure we can successfully troubleshoot your problem, however we are quite some distance from you. You might try to Google search "auto electric repair shops in Virginia Beach". I know there are a couple out there, but I can't remember their names. Your description of the problem makes me think you really need to have a professional troubleshoot this. Good luck! If you need us, we're in Newport News, and the charge for troubleshooting the problem is 85$. Our number is 643-2559; ask for James. Good luck!
