1999 Chevy S-10 S-10 4.3L easy cold starts, difficult warm s

I just had one today that started good cold but extended crank when hot and it was that 2 injectors were leaking down.

Mine was the 4.3 w engine and it was the injectors. I installed the whole assembly, the price was reasonable, about 250 bucks. I have gone the route of power flushing and that only works temporarily if it works at all and I hate doing the same job twice so I always replace the injector as a unit in most cases.
