Yes. I have a short tube. Vs the longer one. I got a used egr and tube last fall. Gotten 2-3 egrs over the years for my equinox collection. I changed egr last fall but not the tube and my stability light/trac control light stayed off for 3-4 days. Then it came back. But, it has not come on in 3-4 months now. So, I just jinxed myself.
I assume if my pic shows egr tube removed you might figure I changed it? Yep.
not the first equinox with cracked egr tube. Ive done 5 equinox head jobs and I think removing heads and touching the egr tube finally breaks the fragile bellows section on egr tube. Maybe.
