Engine Coolant Temperature sensor and the IAC are temperature related components.

Replaced Engine Coolant Temperature sensor, Fuel Pressure Regulator, PCV valve, and cleaned and adjusted IAC valve. Truck ran great. No stalling after engine shut down and there was no surging during accleration and even had positive pressure in fuel tank which it did not have before...then there was a smell of gas in the car, but it continued to run fine until I shut it down and then went to restart it after about 15 minutes. It again began to stall...then you pump the gas pedal and you could clear it. Checked for any hoses that may have come loose. Found one and clamped it but did not fix the problem. Bought a used fuel tank and plan to dig into it to see what I can find. Any clues?

on the 2000 4-runner get rid of it fast! We had the same issue on a Certified 4 runner purchased from a dealer. We ended up getting a trade in on it. Horrible experience in 3 months its cost us over 1,000 bucks. Toyota Corp. will not help you.

This is not the type of response we would like to be passing on. For you to have a bad experience does not mean others would. Toyota vehicles are rather reliable and if you had any bad experience, I would put it down to whom you interacted with.
