If you have loose balancer bolts tighten them up before you oblong the bolts holes or have things fail.
Now the injector, first off the fuel rail pressure charge would be lost to the one or two stuck cylinders which would lead to a hard start as well gas running down cylinder walls thinning the oil with gas.(not good) Once running if they are truly stuck open it could keep needed pressure from other injectors causing poor performance, even though the pump volume would compensate and once again the thin oil because the stuck cylinders can't keep up on a good burn.
