what was the symptoms that led you to change the egr valve? Tryin to diagnose a rich fuel mixture that might be related to check engine code 25,26 and 31 going on at idle and sometimes going off after reving the engine past 1500 rpm. Where is the EGR valve and was it easy to change? Thanks again for all the help!!!!
