v6 stalling

[GR redfearn]

We have a2002 V6 Camry.

When it is warm from a long drive, after we turn it back on it won't idle & will stall.

If we open the gas cap & hood for a few minutes, it is able to idle again.

We have replaced the cat converter but it still does it

Check/clean your Idle air control valve, and maybe try cleaning out your Throttle body.

maybe also check the egr valve.

This is my car too, there's no IAC - but you're right cleaning the TBI might help.
How to: Cleaning Throttle Body, Pictorial

If this doesnt do the trick i can think of a couple other things that may be the problem, You dont mention the CEL being on so i'll go from there with a few wild guesses:

1. The problem only happens with engine hot. So i'd be asking myself (and a toyota manual) what sensors are temperature controlled? check / replace coolant temperature sensor(s), clean MAF sensor, and so on.
2. Your car does not have a seperate fuel filter, it is built into the fuel pump. So maybe this fuel pump filter is clogged? (i think youd change or at least acceess the fuel pump to get to it)
3. valve clearance is too tight (i had your same symptoms on another car and this is what it turned out to be - but unlikely on the camry)
4. Throttle position sensor (mentioned in the post above)
5. One or more fuel injectors clogged or not functioning properl
