Intermittent stalling, usually on a hot day ... a call for ideas!
The rundown;
1996 Integra LS 4 door, stock stock stock.
Recently replaced the distributor cap/rotor, plugs, wires, oil as part of the CA emissions recall/service at an Acura dealership. There is no debris or damage inside the distributor cap (i.e. from a badly sized rotor, or spark corrosion). I don't believe the ignition coil is anywhere near new. Fuel pump is about 2 years old. Radiator flushed around last August.
Yesterday it was warm weather, and after driving a few miles, and on a downhill slope, the tachometer began to jump around, and despite my attempts to rev the engine to keep it going, it stalled on the hill, and I coasted down and to the side on a flat surface.
After about two minutes of sitting with my hazard lights on, it started back up and I was able to make it home by running the engine at around 1500rpm whenever I had to stop. If I recall, the dashboard lights remained on after the stall, which leads me away from thinking it's related to the ignition (key) switch corrosion/heat problem that was causing stalls for some other people.
This has happened several times before, usually on a hot day, and often also while going downhill. During a warm day like that, the temperature gauge will rise steadily to about 3/4 at a stop. When I get going again, it drops to 1/4-1/2. I'm sure my cooling system could use a flush, as there is still some stop-leak residue in there.
It's throwing one code, and that is a TDC sensor (code 8) that is typically always on. According to a mechanic, the sensor is fine and the light is related to some wiring changes from an old alarm system. When the battery is disconnected, the code clears, but reappears when the engine reaches normal operating temperature again.
So to recap:
It stalls when:
It's hot out -
and maybe when I'm going downhill.
Thanks all,

everytime i hear a stall out question i think the same simple thing that no one mentions hardly and i usually get flamed for it, but check the fuel filter. Cuz I had to do the same thing you're talking about(hold at 1.5K at stops) except mine stalled out and almost got me t-boned in an intersection
