[QUOTE=squizxr;5345460]Cheers for the replies lads!!

Temp gauage works fine, but why would the temp gauge not working make it idle at 3k??

On the Focus the CHT sensor supplies the info to the ECU on engine temp, this same info is also used for the temperature gauge and for fan control. So if it was not working this would cause fuelling issues.
