94 s/10 blazer 4.3 stalls when hot

[Roadrage97]

Idle air sensor, throttle position sensor and all egr equipment has been replaced. Plugs wires are good and the truck runs great until it gets up to operating temp. There are no codes being thrown, plenty of spark and fuel pressure is good. It runs fine when warm if you keep your foot on the gas, but stalls as soon as I relase the gas pedal.

 

Any suggestions?

Using an ohm meter, take the reading of the temp sensor (intake manifold near the tstat housing) both when the engine is cold and when it is hot.

 

Post back what the readings are.
