Hey, how do i fix the egr? any ideas besides getting new vaccum line? The check engine light comes on sometimes. My old work has a scanner and it comes up code 32 the egr. Anyone have this similar problem?
how does it idle?....mat are your mat temps....can you run down the road and see the EGR functioning normally?...have you tried replacing the EGR valve?
A stucked open EGR valve could cause the rough idle. I'd remove the valve and check it. Maybe it's only needs some cleaning. You can also check that the diaphragm is moving or not if you apply vacum to the valve's port (preferably with a vacum pump).
