P0278 code cylinder 6
Truck all of the sudden out of no where started to shake at idle my first thought was that it is a miss. Then on hard acceleration blows black smoke with NO tune on at the time, plugged reader in and got code P0278 cylinder 6 contribution/balance. I'm assuming it is a dirty nozzle on the injector. Shake/miss clears out at about 900-1000 rpm. Truck as 247k on it. 50k on injectors. Has ported and o ringed heads, studded, and fully deleted, with bullet proof ficm. Would my assumption be correct?

Kind of confused by that. So your saying take the plug that plugs in to the injector on the top side of the head and swap it with another injector. But then the injectors will fire in the wrong order.

Update: I don't believe it is the injector anymore, leaning towards a electric issue. Wiggled all my injector plugs to make sure they were all connected and it went away and then came back after I drive for a bit this morning...
