Is it difficult to replace the EGR Valve? I found on here instructions on how to replace the sensor and I had that done, but the CEL is still on. I took it back to autozone and the code is still showing "Insufficient flow in the exhaust gas recirculation system". Although the egr valve was supposed to have been "cleaned", I'm thinking maybe I should just replace it. Any thoughts?

yea, but he already said he replaced the sensor (aka, DPFE).

i also had the sensor replaced, and still had the insufficient flow code.

turned out, the egr passages in the TB were clogged with carbon, so after cleaning them, code was gone.
