n 14 celect plus idles uneven when warm

#1
N 14 select plus runs fine for 5or6 minutes when cold. Then starts skipping and idleing up and down. Runs fine at road speed no skip. Any ideas?

Mechanic man says check injectors, injector harness or possibly air getting into the fuel rail.

Says on gasoline engines, it's a typical symptom of a vacuum leak.

+1 on the injector.
Change the filters if they haven't been done very recently. Run an oil sample to check for fuel slobber.

ADD a gallon of DECRON/MERCON AUTOMATIC TRANSMISSION FLUID to the fuel with a fill up.
That may do the trick if you just have an injector fouling.
