My check engine light came on so i used autozones obd scanner and got a p0400 code which was a malfunctioning egr valve. I bougt a new one, installed it, and reset the computer and the check engine light came back on with the same code......any help would be appreciated.
 
This is why I tell people that they HAVE to go to the dealer where the mecanics are trained every month on your car. There is obviously something else wrong! Autozone uses the scanner to sell parts, not fix cars.

Try and un-hook the negative from the battery and leave it unhooked for about 10 minutes, then hook it back up and see if it comes back on. If it does, then I would take it back and let Auto Zone hook it up again and see what it says.
