Has anybody got a HIC valve for sale, please? My Tercel 4WD keeps stalling at idle when the engine is hot

I don't think a faulty HIC valve should cause stalling when the engine is hot. Have you tested it as per the FSM procedure?

Thanks dlb. I just have and it seems to be okay. Would you know what else could cause stalling at idle?

Hmmm. Vacuum leaks are always my first guess but according to the FSM, these are other things to check:

idle speed incorrect
slow jet clogged
idle mixture incorrect
fuel cut solenoid not open
EBCV hose disconnected or damaged
outer vent control valve not closed

It also lists fast idle setting incorrect and choke valve open but those are just for cold engines so those shouldn't apply to you.

This happened with the Acura Integra and mazda rx7 I used to have, it turned out to be the igniter (ignition module) car ran until the motor warmed up, then it would stall. Replaced the igniters and cars ran like normal. Our tercels have this piece inside the distributor. Possible this is your issue as well.
