Hello folks,
This is w245 B1700 petrol 2005/6 with no history, basic runaround.
Cylinder four has a miss determined by pulling HT, removed plug - gap looks huge at 1.1mm although OEM plugs are set to 0,9m which I assume is just under 1mm, not 100% sure as separated by a comma, perhaps denoting something different?
If someone could confirm correct electrode gap that would be great, ordered a set of Bosch which should be here tomorrow.
The coil packs which feed 3/4 has two coils, are these independent of each other, i.e could one coil fail (out of the two) leaving the other working fine?
Complete newbie on this stuff as owned a S124 dinosaur for an age
Thanks for any pointers.
