95 850 doesn't want to start when hot out
My 95 850 with 218,000 miles on it does not want to start when the engine is warm and the outside temp is above 80 degrees. I have to wait 5 - 10 minutes and then it will start but I still have to nurse it up to speed. It chugs. Seems to do alright, or better, when the outside temp is under 80 degrees. Just put new injectors and O2 sensors in.

Why did you replace the injectors and the O2 sensors ??
I'm wondering if you might have a coolant temperature sensor that's going bad and isn't giving the engine enough fuel when warm.
You should also pull the vacuum hose off the fuel pressure regulator and check to see if it looks or smells of gas. If any gas is present the regulator diaphragm is ripped and the regulator needs to be replaced.
