engine code

hello everyone i have a 200 astro van with 225000 i had just replaced the fuel pump (airtek brand) and now i have a P1404 trouble code about the EGR valve ... could anyone out there please shed some light on my problem ......

thanks

its possible that you have a piece of carbon in it not letting it close completly or just a bad valve.
if its running a little rough i would bet on the carbon
