Blowing Black Smoke!!!

[Armycat10]

My 2005 F250 with 163,000 miles is blowing black smoke when I press the accelerator from a stop or if I slow and then need to get back on it. It also had no go power until after it blows smoke. Its acting like it is over fueling. I have an aftermarket Cold air intake, EGR Delete kit (so it’s not the EGR Valve) and have had my FICM checked and it is working perfectly. I took it to a Diesel mechanic yesterday and he pulled it in to his computer and the only Codes it had been for the EGR. I have also taken off my Turbo and cleaned it and cleaned my EBP Sensor and the mechanic said it was working fine. Also said that my MAP sensor is working well within specs. Not sure what else I can do. I cannot afford to take it back had have them work on it.
Thanks for any help you all can give.

Check the injectors. Had one go out and it blew enough black smoke that I could not see behind me. Good luck.

If it's just a little bit of black smoke it's quite possibly just normal. Do you have an aftermarket exhaust on it? When accelerating from a stop you are running on just the motor until the turbo spools, which in turn causes a little bit of over fueling. Does it clear up once you hit boost? If so, i'd say run some rev-x just to be safe and keep an eye on it. It's probably normal. Now, if it's a lot of smoke, you have an injector issue.

Have put in RevX during my last oil change, it depends on the time when it comes to the amount of smoke. If I have my 5th wheel on its a LOT of black smoke and take a few seconds before the turbo kicks in and then it clears up. I have a feeling that its a bad injectors, but I was hoping that its something easy to fix and cheaper!

sounds like its starving for air, if you got no codes it should be something simple,air,fuel, compression makes fire,good luck mate.

Good point! Is it really humid where you are at?

I have cleaned my Air Filter; I am going to get new fuel filters today to see if that helps. Has for humid, not at all I live in Colorado and it has been dry has can be here (lots of fires). Also clean my Mass Air Flow Sensor to see if that would help and nothing. I will let you know what I get after putting in new Fuel Filters, but my hopes are not very high. Thanks

What are your boost and EGT numbers?

[Armycat10]

Not sure what my EGT Numbers are, but I know I was getting good boost when I took it to the mechanic. When I punch it, it will blow LOTS of black smoke for a sec then take off like nothing is wrong. Its takes even longer when I have my 5th wheel hooked up. I thought my turbo was sticking so I pulled it and cleaned it with no change.

Did you check your ebp sensor and tube for carbon yet? You could have the tube restricted enough that it's holding pressure and thinks that the turbo is creating boost and fueling for it when in all reality there is no boost yet.
