SOURCE: when cold, it idles rough, revs high then low! After warmed up it runs fine

if it runs high when you first start it then mellows out,, theirs no problem , all of our chevys do that.... but if its sputtering or you hear a quiet popping noise check spark plugs

SOURCE: Idles rough and is hard to start apears to run better after it warms up. Have replaced the ICO, TPS, and the map sensors with no effect.

You can clean the EGR. No promise it will work. I have an idle problem on my `97 Grand Am Se. Shop told me I could clean it and it might solve my problem. 
Just remove the EGR with the 2 bolts from the top of the manifold behind the throttle body if you have a 3.4 v6 like I do. Then leave it upside down with throttle body cleaner in it. Fill the EGR level with cleaner and let it soak for at least 30 min or more. Then reinstall. 
This will remove any carbon on the inside which plugs the needle from pushing out at highway speeds. Hope this helps. If the problem returns in a week or so then replace with new EGR. New EGR is about $100-200! Cleaning seems to have helped my car did that about 3 weeks ago.
If you have a service engine light on turn the key to the run position on the ignition, pull the fuse to the ECM (batt) and disconnect the wire harness to the EGR. Reinstall it after a 1 min, That will clear all the codes in the ECM and reset everything.
Once you place the ECM fuse back in, start the car. It may stall but let it, DO NOT TOUCH ANY THING. The ECM need to relearn the EGR and engine from all it's sensors like the first time it was started. Just start it up again and it should be like the day it came off the assembly line and will relearn everything.
Good luck and just drive it like you always. If you decide to change the EGR valve, you still need to clear the ECM as mentioned above for the ECM to relearn the new EGR valve. Hope this helps and keep me posted.

SOURCE: rough idle then stalls

Vacume leak or bad idle motor. With the car in park and running with the hood open listen for leaks moving your hand around the different hoses looking for a change in the sounds that you hear. The idel motor also makes the car idel up to 1500 RPM or so right at start-up then idel down, If it doesn;t the idel motor is likly. Check engine light is on when running? Test for codes, Follow code test charts don't skip any steps!.

7.3 powerstroke runs rough until it warms up a little bit then u can push throttle and it will smoke like crazy then take off and run great till next time it cools down and restart


I see these all the time. There is a good chance it is your ECU or depending on the year of your truck it could be your IDM (injector drive module) for earlier models or your FICM (fuel injector control module) for later models after about 2003. Scan for codes even if you dont have a check engine light on the dash. I can get much more detailed information if you are able to get me the codes (advanced auto or autozone scans for free) My company rebuilds these controllers every day. I will be happy to do yours if it turns out to be the problem. Typically the controllers are visible if you pop the hood, possibly mounted to the block or off to the side

This could be the FICM or the injectors. If you have a code reader, it can help determine if its the FICM. You can also check out this thread http://www.ford-trucks.com/forums/899444-ficm-testing-procedure.html
You are probably already aware of all the 6.0 problems. It does sound like a fuel issue. The injectors are unfortunately a problem and very sensitive(don't ever run out of gas). If one injector is bad or going bad, truck will run rough at idle but once rpms get up, the truck will seem to run better. When 2 or more injectors go bad, truck will barely run. In either case, power will be very low at lower rpms.
thanks let me know if this helps

At first the truck idles extremely rough when cold cranked. This went on for a couple of days, now the truck will not start at all. It hits every once in a while while repeated cranking on cold start. ...


Sometimes on cold days if the cranking amps on the battery are low, then it will be hard for the vehicle to start. Also, check the oil level. If the level is low it will create a hard start and rough idle for the vehicle.

Your pre heating circuit may not be working properly. It should cycle for a bit when you first start the engine. Also it may be a good idea to change the fuel filter. Haynes has a Diesel Engine Repair Manual, part # 10330 that may prove to be a help for you. Hope this helps.
