Ive got an intermittent misfire on my mig at the minute despite fitting new plugs, leads and coil pack in the last 6 weeks.
Its not confined to one cylinder

Just trying to establish what else it could be.

Got no fault codes, no EML and no increase in emissions. Got me stumped.
Someone i spoke to today mentioned the possibility of it being the wiring on the speed sensor.


Cam covers were done 2 weeks ago and a couple of the old plugs were soaked in oil.

Is there a possibility that the new coil pack has failed as a result of it having to work extra hard?
Can anyone shed any light on it?

Regards
Ash
