Before you do that try changing the engine temp sensor switch, as these have a big role play. There only £20+

Coolant temp sensor is about £16 and is on the heater inlet hose and the engine inlet air temp sensor on the inlet manifold (not the maf) again faily cheap try cleaning it first though

I dont know where it is on your engine but its at the rear off the engine on theV^ I checked Elsa win if your engine is AJM then it is part of your Thermostat housing.

Coolant temp sensor is on fitted as part of the radiator bottom hose close to the radiator hose flange you will see it from underneath it is a pain as to replace you will have to drain the coolant on this one. As soon as you pull the sensor you will loose coolant.

The sensor is held in by just a metal clip. pull this away from ht esensor and then pry up as it is O ring sealed it will seem to be stuck

Sorry cant post pics this site wont let me.

Hence why i have now given up with it.

Hope this helps

problem turned out to be the coolant temp sensor as the car got to the stage where it wouldnt start cost £19 for the part and an easy job to do however that sorted i still get dodgy driving when the engine is cold
