Oh, I had some vvti specific suggestions based upon my experiences.
I'm sure the calvary will be along soon.

From my experience with the older Toyota series of engines, I usually used to throw in a hearty shot of Diptaene into the fuel tank.
Then give the car a very hard drive in 2nd & 3rd gear to remove carbon build up in the car's internals.

It worked for me a few times with the NCT.

Genuine plugs helped on one I had before. They are €16 or so a pop but well worth it. Try get a secondhand cat also

Coolant temp sensor circuit fault? Or incorrect signal?
Did engine overheated at any stage?

For me it looks like O2 sensor failure.

Catalist will work if fueling corrected.

Check vac line for map sensor.
If cracked will offset readings.

Does your gauge still go up to half way with sensor gone? is it just affecting the signal to the ecu making it run rich and temperature reading ok?
