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).
