1998 RAV4 STALLS - HELP PLEASE

Dear all,
I was a happy owner of RAV4 until last month. The car started stalling. Engine start is OK but after it gets hot it stalls. Firstly mechanics found air intake temperature sensor failure - it was replaced along with air filter and sparks. Secondly they found ignition coils error and they were replaced too. Now no mistakes in onboard computer memory but still it stalls. They say that I have so called "Cold winter" package and they just can't diagnose the problem as their standard test computer can't check additional components. Yes, this car was bought in Canada in 2002, exported to Russia and has electrical heater and maybe some more relevant to cold weather elements. I've attached the schematics of the system and an additional (not standard) valve.
Maybe anybody had the similar problem or has any clue, your help will be highly appreciated.

Kind regards,

Boris.

Boris:

It's good to hear from Mother Russia!

That's unfortunate news about your RAV4. It could be many things.

An easy thing to try: After it gets hot and starts stalling, park saefly then open the gas/petro/fuel cap on the tank. If you hear a big air-sucking sound, and then the car starts and drives fine, you need a new correct OEM Toyota gas cap.

I'd then replace the catylitic converter and the O2 sensors. But we're into expensive guessing.

Thanks for the advice, LugNut. I'll check these tomorrow, that would be a miracle if it could help
What do you think about fuel pump? Possible?

Can your shop loadtest the battery and check the alternator? Either could be the cause...

Of course, the battery was changed first Alternator is OK too. I also asked my wife where she was refueling, she said at BP, so the gas should be OK too.

You know, if you live in climate like we have in Russia, these are the very first things which come to your mind in this case

Air intake issue (clean throttle body inside very well), issue with gunk (big flakes) in oil or fuel clogging up oil or fuel lines.
Replace and flush oil if you suspect oil, replace oil filter then too.

Fuel filter is possible too -- the one under the hood is a challenge to change, but the OEM part is low cost. There are several threads here about doing this replacement, including from me.

Oh, simply to check, are you sure the vacuum system is holding up?
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.
