The fact that it runs OK when the engine is cold is because the ECU
enriches the fuel mixture until the engine reaches operating
temperature.

Your '****y box is trying to tell you that it can't adjust its idle
speed. The idle speed is controlled by an automatic idle speed control
valve which is an electro mechanical business controlled by the ECU.
These things get dirty and also wear out. Remove it from your '****y
box and squirt copious amounts of carby cleaner through it until it
runs clean and then squirt some automotive grade ghee into it for
lubrication.

I seriously doubt that you can test an O2 sensor with a multimeter
(all that will do is test the circuits internal resistance). To test
one you need to see the signal it produces when it is at operating
temperature and subjected to exhaust gas!
