It is beneath the air intake connected to the upper intake, that's probably why you can't see it. The manufacturers don't make things easy. ... 1994 Chevrolet S-10 Blazer

I have a 1997 chevy lumina. i had 2 coded before, po420 and po401. i changed the egr valve, and now the po420 is gone. i just replaced the egr tube, cleared the codes, and now the po401 is back. car sounds better, but i wanna get the code and service engine line off. any ideas?
Well, the po401 is saying is that the egr valve has restricted flow. After changing the egr and the tube, something else is causing the restriction. a more thorough diagnosis is recommended. The po420 code sounds like a possible catalyst failure or a ... 1997 Chevrolet Lumina

I am trying to get my 99 Lumina 3.1 (170000 miles) to pass S & E. Its throwing a code saying that my EGR has insufficient flow in the down tube. I have cleaned that and have used Sea-Foam to clean the throttle body. I don't think the EGR valve is bad. My car doesn't stall or anything like that but i could be wrong. There was also a black greasy something in the intake manifold. Any advice would be helpful! Thanks
The black greasy thing sounds like the PCV valve. It is possible that this would cause the code you are getting. They are also really easy to replace and you can pick them up cheap. If it is the PCV valve, it will have a rubber hose running to it, th ... 1999 Chevrolet Lumina
