I got the dreaded 71 CEL code

[DeclansDaddy]

Hey guys my CEL came on yesterday and I disconnected the battery for a while and it went off til tonight. Got the 71 code (EGR malfunction). I plan on checking all the hoses out but if I find nothing there what are some common areas to check first. I guess obviously the EGR valve but what are some more common causes for this code. Thanks.

Check the vacuum lines that go to the actuator looks for any cracks that what we found when my buddy got the 71 code

Oddly enough the light went off by itself. It came back on a few different times but is currently off. I haven't found a pattern, like rain or extreme cold so it definitely has me stumped. I've looked over vacuum lines and haven't seen anything obvious.
