Replaced the LIM awhile back and keep getting a P0401 trouble code which is Insufficient EGR Flow. I have checked and checked again all of the vacuum lines. Anybody have any other ideas?
 


Our EGR is controlled from the computer not a vacuum line.

Pull the EGR off and clean it really good and install it again and clear the code. If code comes back, then you'll have to dig deeper into the issue.
