Mis-firing after putting in garage, need advice urgently!!!
Discussion
I have a Ford Focus style 1.6 petrol 2009. Today I had a mot test at a well known centre. recently I had the engine light in the car come up. I had the car through a diagnostic test and I needed my spark plugs and coil pack/ leads changed. All at this point the car was still running fine with no noticeable faults while driving. The spark plugs I changed myself. When I got the mot test I asked for the coil pack and leads to be changed to remove the fault in the car. I passed the mot test and after passing they changed the leads and coil. When I received my car back as soon as I started the engine the car was jerky and blantly mis-firing with the engine light now flashing.
The guy said it started to mis-fire after the mot test when they moved it from the car park into the garage to change the engine part roughly 10m and it just so happens it was a problem waiting to happen. I've left my car at the garage and they are going to look at it again in the morning. Am I liable for this or not as from my point of view the car was running smooth before I took it in I've asked them to change a part and now I've got a big and costly headache on my hands with what feels like a serious problem

Possibly a dodgy plug, lead or coil pack. I bought a cheap (£20) coil pack for an old Focus that was faulty straight out of the box. Who supplied the parts, you or the garage?
If the garage then i'd say they're liable to replace the faulty part. If you supplied them, then i'd say it's on you to sort.
I doubt it's anything major. Leave it with the garage to sort, i'm sure it will be a pretty simple fix.
Certainly won't be two leads accidentally swapped over as the car wouldn't even run.

I'd go for the cr@p coil pack, if i had a penny for evey one that failed in mins rather than years i'd have a LOT of pennys!!! allways and i meen ALLWAYS go at least for a mid price range coil pack, never the cheapo ones in plain boxes, a zetec wil run with 2 leads swapped but i doubt you'd even get it to move before it stalled, it certainly wouldn't be just a misfire, it'd be rough, really rough !
No diagnostic test wil tell you what you have to change ! it will say missfire cyl 1 2 3 ect or intermitant misfire or random misfire if you use a low end code reader but it certainly wont say change the coil leads and plugs !
If it was read with a high end reader (IE a decent one) it will be more specific IE P1360 Ignition coil A secondary circuit malfunction, P1352 Ignition coil A primary circuit malfunction ect ect and then the mechanic will work out from that what the issue is, the reason you pay more at a large garage is they have the (way) more expensive equipment that will narrow down the issue but not will tell you exactly what to change and certainly not the broad range of items that you listed, that broad list will be a mechanic using a low end code reader and just fobbing you off with a general area of where the fault lays knowing full well he wont get the work to fix it.
Not that i expect the OP to return to this thread, they rarely do.
