You actually do want it to pull timing if you have knock and on the Zetec and Duratec they work perfectly on about 99% of the Foci

Its my opinion to leave the knock sensor on as it is a HUGH safety for your engine , yes you may see some knock on gear change but thats perfectly normal because of tip in timing adding timing on tipin in among other things

Please leave your KS on at all times unless you have a SVT
