New member here with two focus's in the house and my wifes has an annoying problem.
Basically it will start first time but unless you give it a lot of throttle it wont stay running for a minute or so. After that it runs perfectly. No fault codes present either. So far I have,
1. Changed the glow plugs
2. Changed Cylinder head temp sensor
3. Sworn a lot
Has anyone else had this problem and can shed some light on it before I rip anything else apart?
Also, as other cars I have worked on have had coolant temp sensors rather than head temp sensors, does the Focus head sensor live in the coolant flow or is it meant to be in a dry housing? I was expecting a flood of coolant when I took it out but nothing. Just want to make sure there isnt a cooling system blockage.
