just about a year ago my CEL came on, it was egr flow insufficient, so i went down to the local advanced and got a new replacement DPFE. CEL went away, 2 months later it came back on again, this time said egr flow excessive. so i took out the egr valve itself cleaned it and checked the vacuum lines, everything was fairly clean. After i cleaned it i got a very small improvement in power and mpgs (like .25 mpg) however the CEL is still on after getting it cleared. Anyone have any idea whats going on? its driving me crazy to see that G.D. CEL on!
