No codes or trouble lights. 209,000 miles with a pressure regulator,fuel pump, and thermostat at about 200,000 miles. The engine was hot and it will drop below 500rpm and die. Start with throtle pressed slightly. Then dies if released. Same when coming to a stop sign.

Re: Low idle and dies when hot
Check and clean your idle air control port. If you pull off the air intake port and feel inside the throttle bore you will feel a hole in one side or the top. Clean that out real well with a brake cleaner or carb cleaner solvent. You may also want to clean out the the throttle bore itself. That should at least help with your idle problem.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Check for correct fuel pressure.
If fuel pressure is low could be bad fuel filter, fuel regulator or pump.
If fuel pressure is correct could be bad MAF sensor, injectors, O2 sensor or vacuum leak on inlet manifold.
if dies immediately when u put it in drive then whats happening is the torque convertor on transmission is lock and need to unplug the electric connector on the transmission cause that's all it controls, if dies in park u most likely its Idle air control valve on your throttle body, if it does it when fully warm ur injectors cause that .... just try to clean idle air control valve first and unplug transmission connector first u should be running better
hot engine or cold, or both? 180F+ is hot.
Shuts off, idling or on the fly, say at 30mph right foot down it dies?
just clue here...
engine stalls. is complex. but in the macro its below, using tools finds the reason,, but you never said did it restart easy./??????
1: lost of engine compression hot engine, (or overheated)
2: lost 12vdc electric power at stall (caused it) dash goes dead. ?
3: lost spark, test spark at the failure point. if dead trouble shoot speak.
4 bad fueling, too lean (say the fuel pump dies) or too rich.
too rich causes wet spark plug tips. (lots of causes )
5: stalls due to idle RPM too low, below 800 is too low.
too low idle rpm is caused by many things, but top 2 are.
A: EGR stuck wide open, clean it, as the books shows at 60k miles
B: ISC stuck closed. (same deal clean it)
now repost and say when it stalled,
at a read light or flying up a hill wot, wot= wide open throttle.
and when it dies, is the restart easy or hard.
