Help! lope idle and heavy black smoke... Im out of town doing some training need help

ok this morning I noticed my truck was smoking pretty bad in traffic after stopping noticed has a lope idle and smokes at idle. Puts out heavy black smoke during light acceleration. Its has code p0275 #5 cly contribution. Edge insight is showing the ficm at 48v. fuel pressure is at 69 psi. truck has 155k miles. thinking its the #5 injector. dont have anyway of getting it checked til Thursday as im told by the local ford dealer. Should i just order an injector and replace the number 5? Im away for 3 weeks and have a hobby shop on base to work on it, I need to get it fixed before i head home. any help is appreciated. mods in sig.

You can unplug it and see if it helps with the smoke. I'd guess that it is over fueling.
Can you do a buzz test?

Most likely injector crapped out. My 04 did the same thing. Parked outside a store, left it running fine, came out, hard lope idle, huge clouds of black smoke, my insight showed it was cylinder 4 bal/cont. local mechanic changed the injector, now truck runs fine.
