I keep getting the insufficient egr flow code. I have replaced the egr valve. I have great vacuum at the manifold. I have cleaned the maf sensor. I have had the code cleared and the car will run fine and get great mileage then the light will come back on a few days later and then the mileage goes bad. The car runs fine! I am out of ideas. I have also tried the Seafoam additive and a new air filter. This is driving me nuts!!!!
