P0401 - EGR Flow Insufficient
P0401 - EGR Flow Insufficient
Hello,
I have the code P0401 showing in my Blazer and I'm wondering what is the best method of cleaning the ports on the manifold. Would it be better to remove the EGR valve and get into the ports with some throttle body cleaner and a toothbrush or would I have to remove the intake plenum? I have a 1995 S10 Blazer 4.3L CPI (spider injection) 4x4
