The ignition coil has just failed on my 2002 1.6 Focus after 73000 miles. The engine management light came on and the engine started firing on 3 cylinders. My local garage said he was regularly replacing coils in 1.4 and 1.6 Focus's. After reading about inherent problems in Focus's, the failure of a coil was not one of them. Anyone else heard of this fault?
Yes the car could be started and driven, in fact my wife drove it to our local garage but you knew you were on three cylinders! A new coil cost £50 and was a genuine Ford part. The diagnostic test cost £25 by my local independent garage. All appears OK now. Just took it up to the rev limiter in second.
I had to drive to Liverpool when my coil pack went and so far so good.
As has been said, common failing point when they get a few miles on. Mine was diagnosed my removing all the plugs and one didn't make a difference. Ran like a pig on the way there but I got no engine management light. I reached heady speeds of 30 mph and the car was not happy at all especially when most of the way was the very fast East Lancs Road!
it's a 2 minute job, unplug ht leads (replace at same time as coil pack), unscrew 4 torx screws, remove metal securing clip from underneath coil pack, insert new pack, re-screw, replace metal securing clip, reconnect ht leads in correct order (coil pack is marked cyl's 1-4). voilá - wish all jobs were that easy!
