I've got a fault code which is suggesting that my coil pack is at fault but I've replaced it and the car is still giving me the same code and runs like a bag of crap. Have I just got a dud coil or is there a possibility of a bigger electrical issue?

Have you checked the condition of the spark plugs? They are cheap to change but get genuine ford ones. Is the coil pack an ebay special, just curious

L00ney123

No I got it from a scrap yard. Not checked them yet been too windy out bonnet keep getting blown off the stand lol

H3lsing

It's possible the coil pack is gone, you might get lucky with another if you can exchange it.

probably why focus was in scrappy lol

Gone through 3 coil packs now and still a bag of shite. Got a set of bosh plugs (I don't like them.either) and a set of leads from euro car parts so will fit them when I finish work at 10 and hope for the best

mgmidget

have you tried to clear the fault with reader?

I've seen the same fault on a Mondeo and it's power fault. Probably a bad relay and you can make it worse by turning all the electrics on/off while it's running.

L00ney123

Yes I've cleared the fault with my snap on diagnostic machine it's had a coil pack leads and plugs and still comes back with the same fault code, ready to.scrap it

Running bad all the time or under certain circumstances?

I read somewhere that spraying some lithium grease into the end of the leads on both IC and SP ends will act as an insulator and repellant for water & dust between the IC, Leads and Sparks.

I'd do the plugs, leads and coils with something known to be working.

Check the PCV Valve and Crankcase Breather pipe at rear of engine - if this is split, it'll cause a vacuum issue and thus shitty running conditions.

Try removing KAM fuse for a few mins and/or disconnecting battery so that it forces a relearn.

If you have an OBD2 Bluetooth adaptor - download an application called Forscan Lite for Android and link it up - this app will give you an overview of a load of different sensors and codes from units you wouldn't think was possible. Should give you the right idea of what's going on. Check Idle Control Valve readings, MAF readings too.

It's on idle and low revs it clears up on the higher band of the rev range. I will check all of these on Monday morning. It's had new coil plugs and leads and it also struggles to start when cold

Might be worth getting the alt, starter and battery checked. Most garages and halfords can do this for free usually.

sedge

did you ever get this sorted mate as i have what sound like the same issue

L00ney123

No mate ended up scrapping it

sedge

ok thanks for letting me know

big_wasa

I've just done an st with the above fault and there was a short in the wiring causing a voltage drop.

where abouts in the wiring was it roughly
