Good morning and welcome to JustAnswer!!

if your sure the EGR valve is sticking then I would replace it since you have allready cleaned it..

Customer: replied 1 year ago.
would something else be causing the egr from closing on start. i know it is pushed open when ignition is turned on. appears it doesn't retract after start up. does it several times a week
Customer: replied 1 year ago.
appears something is hanging up, truck does not want to rev up

What codes are setting and have you had the ECM updated to the latest software?

Customer: replied 1 year ago.
I think one was p4050,egr related, II don't want to throw a 500.00 + part at it hoping to fix it. The last PCM update was a J35 recall. ( 72351435BK , Recall J35, Code 23132, Date 5/3/2010 )

Can I run the truck with egr unplugged to see if issue at start up goes away. What codes should I expect to see with this unplugged
Expert:  -Brad- replied 1 year ago.

The EGR can open @ idle and likely not the cause of your issues... WHat codes are setting?

Brad, your not answering my questions or making an attempt to point me in the right direction, are you a diesel mechanic ??
It is a issue that happens at start up, engine will not rev up and engine sounds like it is in regen or something. If I keep shutting it down and restarting it will run correctly without setting a code
Expert:  -Brad- replied 1 year ago.

The EGR will not cause any idle issue, you can even unplug it and it will still run fine... You have other issues and I would start with checking your fuel delivery system..

Brad, I don't have a problem with idling ! It will idle fine and make a funny intake noise ?? Is J35 flash the latest upgrade available for the 2009 cummins. I'm going to unplug egr valve and see if problem still exists after a week or so ??????
Expert:  -Brad- replied 1 year ago.

There are updates since the 2009 flash and I would suggest for you to have it updated and see if your issues still exist..
