3pt1lumina Posted October 10, 2009 Report Posted October 10, 2009 I got this code tonight which is EGR Insufficient Flow on my 97 Lumina w/ 3100. The car has 159k so I am assuming that maybe I just need to take the EGR off and clean it out? I've never come across this code on my vehicles before, so I am curious if anyone has had this code before and what they have done to correct it? Thanks! Quote
slick Posted October 10, 2009 Report Posted October 10, 2009 Pull the EGR, and clean down the ports from the intake manifold to the EGR. Use some of those little pipe cleaners to scrub at it a bit. Quote
