I have a ford focus TDCI 1.8 w reg and the coil light keeps coming on up to 3 times a day, when the light comes on all power is lost. I have to pull in switch off and re-start, then it ok again. Also it seems to be misfiring or having an intermittent loss of power, any clues?
I've had it at my local garage 3 times now, they have done all the diagnositic checks and said it's ok????
It's getting a bit dangerous cos i cant predict when it goes.
I've been told it could be one of the following :
crankshaft sensor , throttle sensor, camshaft sensor, fuel solenoid, injectors, fuel filter and flush of system,
