Rough idle and bellows out black smoke

[charlie.thomas]

I have an 07 6.0 and just recently within a days time my truck started pouring black smoke out of the exhaust and a rough idle. It shows code P-0284 Calibration/ balance cylinder 8. I have put a 5" air intake on it, bullydog gt programmer, 4" turbo back straight exhaust. I feel it being an injector but up for all suggestions. Any takers on advice?

do you have egr delete and such?

[jermcd]

also, how many miles?

[charlie.thomas]

I have 118K miles on it. I have the EGR delete kit ready to be installed and also an oil cooler to be installed. I plan on doing it in the next week or so because been working 7 12's for 3 months, my EOT is a little higher than my ECT. EOT- avg. 190 to 200 and ECT- avg. 180 to 188 all depending on the load on have on the truck

Also, it doesn't smoke at idle. It is pouring out the black smoke when you are accelerating and steadily driving. All except at idle it runs like it always has, I have noticed fuel mileage being worse though, that's why I assume injector.

Unplug #8, see if it stops pouring smoke.

Sent from my phone that somebody didn't help me get.

black smoke is an indication of a lack of air. my first thought would be to check the ebp sensor, tube and pigtail. there is a hose at the bottom of the coolant expansion tank that often rubs on or coolant drips down ont the harness and can cause the issues you speak of. could throw the number 8 contribution code as well. you can see it without taking anything apart. it's just one among many possibilities. but usually black smoke is caused by an issue with a turbo control input, like ebp or map, etc..or vgt solenoid, or the turbo itself. does it boost ok?
another thing you'd want to try is returning the tune to stock. i'd probably do that first before anything else. if that's not it, have a peek at that ebp harness right under the expansion tank. usually an injector will cause white/greyish smoke that reeks of diesel. but it is possible to be an injector issue as well. but i think those quick visual checks and returning to stock are warranted

[charlie.thomas]

I returned the tuner to stock and it runs smoother but getting a lot of grayish smoke even when it's idling. I will try looking at the harness and tubes as well. Once I figure out anything I will definitely ask for more advice and let y'all know what it's doing.

You're EGR valve is sticking. Pull the valve and clean it and put it back in. After you do the delete, it won't matter but cleaning it will get you by until then.

I cleaned it Wednesday and put it back in and it cleared the code for a couple hours and went back to same state of problems.
