I’d replace the ecu temperature sensor under the third runner of the inlet manifold- they don’t last forever and my car had running issues just after starting before replacing it.
Makes sure you buy a Bosch one- the pattern ones don’t last long and sometimes don’t work at all.
Ignore the internet that says you need to remove the inlet manifold to fit one, all you need is a deep socket that fits the sensor and perhaps to move some wiring or of the way.
Cheers
