jjmmww1 Posted May 28, 2017 Share Posted May 28, 2017 Have had this problem for a while now and has started to get a bit worse but it only happens for a few days then the car drives like normal for a few weeks,months then comes back What it seems to do is just rev itself up and down a bit or when driving the revs just drop a bit and seems to lose power for a few seconds but this only happens when the engine light comes on and when the light goes of the car drives completely normal. have a video of it doing when sat in traffic can upload later and will also read the codes and post them but does anyone have any idea what could be causing this? car is 55 plate focus 1.6 petrol at 118k miles Quote Link to comment Share on other sites More sharing options...

Dave1981 Posted May 28, 2017 Share Posted May 28, 2017 That error code points towards either a fauly in the wiring between the coil pack and the ecu or a faulty coil pack.. Trace the wiring and if there r no obvious breaks personally id change the coil pack reset the code and see how it goes. Quote Link to comment Share on other sites More sharing options...

Dave1981 Posted May 29, 2017 Share Posted May 29, 2017 Has your car got the the single coil pack or individual ones, my 2010 2.0 titanium has individual coils on it hence why i ask. Quote Link to comment Share on other sites More sharing options...

I'm not to sure but ive had a look and theres a cable tie currently holding the wire round the coil pack so maybe just a lose wire. as far as I can tell im guessing its a single 1 Quote Link to comment Share on other sites More sharing options...

Devonboy Posted June 1, 2017 Share Posted June 1, 2017 The cable tie around the plug looks suspicious to me You can buy a new plug from eBay or from :- https://www.simtekuk.co.uk/index.php/automotive_connectors/ford_connectors/?k=:8:229617 The coil is easy to change, Quote Link to comment Share on other sites More sharing options...
Micro Posted June 2, 2017 Share Posted June 2, 2017 4 fasteners hold the coil pack on, and the OEM packs are numbered (on the top) for which ignition lead goes where - but better to take a picture too. I'd replace that plug too. I replaced mine with a "Hella" aftermarket part as the Bosch part was going to be 2 weeks+ from ECP.
