04 engine has a strange problem

My 2.4 four cylinder runs just fine when its cold. After it warms up, the engine wants to die. There is a sweet spot on the throttle that will get me back home. Very small. A little more then a idle. Any more, or less throttle, and it dies. I think this is thermal related, and likely ignition. Fuel pressure is good. Throttle body sensor looks good. That is to say, a smooth advancement as the accelerator is pushed. The only code I get relates to the knock sensor. There are 2 temp sending units. I thought about changing them. The one on the back of the head concerns me.
Before I start throwing parts at it, like a blind man throwing darts in a dark room, Has anyone seen this before?
Thanks

 

Maybe... IIRC, yours is a drive by wire throttle, anyway, what he did was turn the key on and slowly press the acceleator pedal to the floor 3 times, it is worth a shot

 

any codes popping?
