EGR insufficient flow. EGR valve was pretty bad looking seemed a bit sticky when opened so I replaced it along with gasket. reset the computer but check engine light came back on code p0401 again. I know you can test by pinching the yellow striped hose at the throttle body to see if the solenoid is bad. The engine will stumble a bit when you pinch it closed, or so I am told. However when I pinch the hose, nothing happens. I do notice that the car does idle kind of roughly. Anyone have any insight into this issue? Thanks in advance.

Danc83 is an unknown quantity at this point
Hi, I am having the exact same problem. No stall or shudder when I pinch the yellow hose. I've also read this article people have posted on here before: http://www.myhyundaiforums.com/TSB/xml/06-36-006.swf

It's difficult to test the vacuum when the hoses are so corroded they will break when removed so I'm shopping for replacement hoses now and I will just switch them out and check the metal pipes for blockages. Since my egr valve is new I am looking at buying new vacuum valve and solenoid. But where to buy the hoses and know if the solenoid/vacuum valves are right for my 2003 4cyl?
