Here is the code

[NathanTroy]

My 2004 check engine light is on!

Here is the code: EGR Flow insufficent

Where is my EGR valve or valves? I heard that I can clean then?

Any help would be great!

yea that thread should definitly help. probably not just cleaning the egr valve. But try that if the code comes back, replace the sensor. Its not too difficult of a fix but there are just several things to check. PM if you need more help, I just solved this problem with my car and didnt cost me any more than the cost of the sensor (~$50) and the cost of a gasket. but good luck!
