I need helping location the EGR valve and the surrounding tubes so that I can clean them out. My 2001 threw a CEL code "EGR Flow Insuffiecent (Exhaust Gas Recirculation Flow Insuffiecent). I have read that this is a common problem and often times it just requires a tube to be cleaned. Any help locating the EGR valve or tips on solving this problem would be a great help. Once again its a 2001 V6 with about 70k miles.
