Did you test or replace the EGR temp sensor?
Clean out the EGR filter?
Check all vacuum lines running to the EGR?

where is the egr filter and the temp sensor ?

 

Search and you will know.
Try "3VZE EGR temp sensor" and "3vze EGR filter" I bet you find what information you seek.

Not really. The EGR system on the 3.0 is very simple. Most of the time the failure is the temp sensor or a simple vacuum issue.
