cardoor   10 #1 Posted November 21, 2012 Especially when I slow down or its idle, its a Ford Focus 2.0 petrol 02 plate, just been serviced, MOT'd and passed with no advisories.  Could the garage have done something either accidentally or purposely ?

cardoor   10 #4 Posted November 21, 2012 Take it back imediatley and I'm sure they will sort things out for you.  They won't without me paying them despite it only being serviced and MOT'd last week. They were quite avid the problem is nothing to do with them. Share this post Link to post Share on other sites Share this content via...
Isabelle   10 #5 Posted November 21, 2012 Did the service include changing the spark plugs? I don't know much about cars, but when mine was stalling and losing power it was the spark plugs and HT lead needed replacing. Share this post Link to post Share on other sites Share this content via...
sierraman   11 #6 Posted November 21, 2012 The garage are right, you took it in for a service, if a fault came through their workmanship thats fair enough - its their fault. Otherwise its probably the Idle speed control valve/vacuum leak or possibly if it only does it from cold the coolant temp sensor.

muddycoffee   10 #7 Posted November 21, 2012 Sounds like you may be ready for a coil pack. All petrol ford zetec engines are only guaranteed to last around 5 years before needing another one I have been informed.  Symptoms is exactly what you are describing. Probably nothing to do with your recent service unless you were charged and extra £80 to include a new pack as well.  Exaclty as Isabelle says, you get a complete set of HT leads, the electronic ignition unit and plugs.
