frown coil pack problem Ford Focus 2002 1.6 zetec

Coil pack problem - Ford Focus 2002 1.6 zetec

For the 2nd time in two weeks the coil pack on my ford focus has failed.
The histrory of the problem is as follows:
April 2005 - Purchased car from Ford dealer 2nd hand
June 2005 - Engine misfiring - Coil pack replaced by Ford under 3 month warranty
November 2006 - Engine misfiring -Coil lead replaced
June 2007 - Engine misfiring -Coil plug replaced
July 2007- Engine misfiring - booked in to mechanic this evening

Also I seem to have a problem since the start of the year where on average 3 times a week the Speedometer will suddenly hit zero for a short period. Usually while i'm doing speeds 40MPH+.

Tips that I have picked up from searching on google are to check the ignition cables are not touching, check the cable from the battery is secure.

Can anyone else help me with this issue. Many thanks

That's a sorry tale, unfortunately things have been taken in the wrong order- it's a plug that causes the lead and/or coil pack to go down so this needs to be isolated and replaced then the lead/coil pack.
If just the speedo drops it's usually the vehicle speed sensor.

Thanks Ford Tech.
Unfortunatly I only got to see your reply this morning. My mechanic has put another lead on last night and told me to see how this pans out. It felt fine coming into work this morning. Do you recommend we look into replacing anything else now the faulty plug is replaced and a new lead put on before the circle of events happen again?

If the source of the HT concern has been replaced, hopefully you should be ok.

Still if the speed drops to zero still as fordtech says its normally the speedometer sensor on the gearbix that needs replacing, i did this and all is now fine!
Fordtech, any ideas what would be the problem with a non working fog lamp? Tried new bulb and fuse and the switch tests fine. Just recently had all these problems all at once!!

Could be the bulb holder, you need to see if anythings missing from the plug (ie live or earth) and go on from there.
