LM7 5.3l 4l60e dies at stop when warm
I put a 2003 LM7 with 4l60e in a 64 chevelle. Engine runs perfect until it warms up. After it warms up the car still runs great except when I come to a stop the engine will either die on almost die. Doesn't do this when the engine is warming up.
Its like the idle speed is too low after the engine warms up.
Anyone know of what gremlin would cause this symptom. Its real agravating, as the engine runs great except for this one issue.

Speed sensor is verified working, throttle body is clean, no vacuum leaks present.
How does one go about adjusting the throttle plate? I presume it needs to be open a slight bit more?

the idle screw is set to where it should be from the factory. if you were to open it up a bit then you will have to get the pcm tuned so it can know lowest tps position..

Have you verified the fuel pressure? What is it set at?

I have seen the FPR go bad more than I would expect. Worth a look at the pressure when you start it and when the problem starts happening.
