I have gotten a "P0402 EGR Flow Excessive at Idle" trouble code twice in the last week. I got it Tuesday, cleared it, and it came back this morning. Has anyone had this code? What does it mean? My L is a 2002, stock with the exception of a 3# lower pulley and a drop-in K&N filter. Thanks guys.

You may wanna put a vacuum gauge on the line going to it...It's a possibility you could have a leak.
