Bronco 2 will not run after warm up

[str8klh]

hello, I have a 1986 bronco 2 when I start the motor when it is cold it runs just fine but as soon as it warms up .when I try to take off from a stop it spits and sputers like it is not geting any gas. I have replaced the fuel regalater,and tpc, and checked vacum lines, and reset the computer and I am still haveing the same problem.Can someone help me.

Replacing the ECT sensor worked for me.

Mine was doing the same thing, and after beating my head against the door, I checked the spark plugs. Mine were worn out and the gap on most of them was around 100K. Factory gap is .42 to .46, and after replacing mine it runs fine. It would start fine, run good till it warmed up, then it did not want to accelerate, it would spit and sputter, lacked power.
Now it's running great. Take a look at them, and see what they look like.
