Yep! Pull the egr off, clean the port under it all the way to the throttle plate, I use a length of steel coathanger. Put it all back together, reset the codes, if light comes on again, replace the EGR position sensor, thats the one the two small hoses from the exhaust plug into! On LS you need to remove the throttle body to get at the passages, clean with an old speedo cable attached to a drill.
