I serviced the wifes focus last year. Put new plugs in and it was running on 3 where as before it had been fine. Turned out to be a knackered coil pack that gave up the ghost due to the new plugs.

Aaaargh! Yes, Ford Focus 1.8! I hope coil packs aren't dear on these then.
BBROWN, your wife's car ever had any speedo problems?

what year is your focus? I assume the speedo just drops to 0 and comes back now and again.


I had a 2002 and the common problem is the speed sensor on the gearbox. Annoying job as they normally snap off on the gearbox. The part is only £25 from ebay.


I had it replaced and was fine, my step father has the car now and had to fit a new gearbox, the speed sensor on that box had gone too.
