LB7: EGR valve probelm

[JoshDizzel]

Whats up im new here. I have a 03 LBZ duramax. Engine light came on a month ago. Code reads to what i can remember EGR valve Closed or stuck cant really remember. Just wondering if anyone else has encountered this problem and how easy it is to fix. Also seems like i have lost some power. I have read that when the EGR valve sends the code to the computer it decreases the fuel pressure. Is this true? And how long would it take to fix? And around how much?

EGR codes are not easy to trouble shoot and fix. Having the code will help.
Jump over to the diesel place (just don't stay there...) and do a search for EGR code. You will find enough info to make your head spin for days...
