No power/rough running when cold

Hello everyone, I have an 2003 F-250 6.0 with 128k that runs very rough and no power only when the motor is cold. I have unplugged the egr no change and no codes in the pcm. I put a programmer on it and it magnified the problem plus blue smoke. If I plug it in at night it's just fine in the mornings. Can anyone explain whats going on? Other than that the truck runs like a top and i love it. Please help.

Thanks Ken

the 2003 and early 2004 6.0l engines in trucks built before 9/29/03 have injectors that cause this problem. I would say you need at least one injector but most likely more as far as i know the replacement injs were not updated so even if you get new inj they may still develop the samed problem also low fuel pressure wipes injectors out fast. I hope this helps you

Thank you Psdtech, so if I replace the injectors this can happen again because theirs no updated injectors out for these engines? Whatís the correct way to fix this problem? Can you explain why it runs fine when the engine is warm and doesnít when itís cold. I know Iím asking a lot of questions, but this is got me wondering about these engines now.

If it were the injectors

there is a 99.99 percent chance it would NEVER clear up. If it does it cold and not when you plug it in at night its a glow plug problem. Check them out. I have put a few GPCM's on the 6.0's.

Oh yeah, not aware of any injector updates on our 6.0's yet. Don't know where that came from. 7.3's had updates back in the day.

I disagree jon, most of the injectors i see fail only fail a powerbalance on cold start. Some of them in an early failure may only dropp out for 30 seconds, and then clear up. They do get progressivly worse with time, but this gentlemans problem sounds just like an injector or two failing to me.....
