lmdew Posted November 27, 2011 Share Posted November 27, 2011 The head port could be blocked. Can you pull the line off the EGR valve and start the engine see if you are getting flow out of the line. Link to comment Share on other sites More sharing options...

idosubaru Posted November 28, 2011 Share Posted November 28, 2011 i had a 97 automatic that was hesitating badly, wouldn't down shift, and i *think* it was giving some EGR related code - because i replaced the EGR valve with new, gasket, and solenoid to no avail. i finally replaced that little quarter diameter sized filter on the passengers side vacuum hose, $7 from Subaru and all hesitation went away. never had a problem again and a friend now owns that car. i'm not familiar with EGR so listen to others that offer diagnosis, etc - i'm just relaying one experience i had.
