Check the ECT (engine coolant temp) sensor harness multi plug connection,as this is known to fail due to vibration. Also check all air/vacuum connections.
If all above is okay then you may be best to have a diagnostic check carried out.
This should then show a fault code ( ie P ---- 4 numbers) which should then relate to the problem ( could be one of the many sensors).

Far better than previous Vectra. Now with decent handling and an excellent ride. Plenty of safety kit. Roomy in the front. Big boot. Good looks.
