Testing The Coil Pack

[mikeshe]

Had a Lambda Sensor fault code and really rough tickover, emissions were stinking. Fitted a new sensor and now have no fault codes but have a misfire at all speeds. I suspect a coil pack as it feels like it's more than one cylinder misfiring. What is the best and easiest way to check the coil pack before I start spending too much money?

Thanks

hi

I usually use a spare old spark plug connect to ht lead and see if they fire .

Thanks mate, all sorted now. Previous owner bought a cheap unbranded coil with a date on it of 17/10/09 so it hasn't lasted two years. Just ordered two Bosch ones and new leads.
