Because if not, the IAC will not function, thus cutting off the engine.
With a not standard vacuum sensor, that might be something worth looking in.

When doing flush with oil, don't forget to drop pan and clean it.

check all the wires and connectors related to the Emission System, making certain there is no loose or severed wire.

Clean the throttle body and the IAC valve, Most likely the IAC valve is clogged with carbon.

Yesterday went to Toyota dealer. They found nothing, the car stopped stalling. Checked onboard computer - no error record.
Today I started engine (at 10°F), tried to start but ... it stalled again...
More ideas?

What advice you already have followed and what did you do exactly.
It is hard to think along with such cryptic info.

What did the technicians do other then reading out codes and talking to you?

if your IAC and TB is already been cleaned. Check the hoses related to vacuum. It could be loose, it could have hairline cracks or worst it is returned in different ports by the mechanic.

When you cleaned the IAC and TB did you reset the ECU (remove the battery terminal for 15mins) ?

the other thing that is worth a check is the exhaust manifold, look for hairline cracks, i had the same trouble, and it was air getting in the crack on deceleraton, lambda sensor recorded too much air and over fuelled it causing it to flood, two trips to the garage never found it a penpusher mate did.

OP, have you checked the distributor cap? Take it off, inspect for cracks, junk inside, moisture, and/or worn internals. Inspect rotor inside cap. Replace if necessary.

Also, originally you mentioned it stalled when it got hot.. That could be a thermostat issue. Had that problem with an old honda I had.

Can there be water in the gas tank? Very common, especially in cold weather, if the tank is not full all the way condensation can build up. Then it will fall to the bottom of the tank and there you go, you got a problem.

Hi guys,

Sorry, I had a flu, had to postpone all works for a few days
It's -4F in Moscow, quite cool

Yesterday we cleaned the throttle body and the IAC valve and checked wires (as much as possible). It stopped stalling a day before, so it's impossible to say if we did any good

Today I ran about 100 km, no sign of stalling. So I keep my fingers crossed and ordered NGK spark plug wire set and a fuel filter as well just in case to be sure that we missed nothing.


By far no sign of stalling
Unfortunately, we haven't found the reason of failure

Thanks a lot for your help, guys!
