Hi

I have recently bought a 2007 2.0 tdci focus and the first morning i started it i had to heat it up three times. This has improved and only have to apply heat once now.
Does anybody know where the heater plugs are ? usually 4 inline on top but i cant see them lol.
Also it is ticking over uneven, is there anything i can take off and clean? airflow meter/sensors etc.

Many Thanks
Paul
